The Pekin. While this variety wants to be of good size and to have length, breadth and depth of body it is somewhat more upstanding than some of the other meat breeds, showing a definite slope of body downward from shoulders to tail. The back line of the Pekin should show a slight concavity from the shoulders to the tail and the upper line of the bill is likewise slightly concave between the point where it joins the head and its extremity. The shoulders should be broad and any tendency toward narrowness at this point must be avoided. While a good depth of keel is desired, the standard does not call for so deep a keel as in the Aylesbury. As a matter of fact, however, the winning specimens as seen in the shows are not as a rule as erect in carriage as called for by the standard illustration, there being a tendency to get them almost if not quite as deep in keel as the Aylesbury. In fact, some breeders seem to strive for a low down keel approaching a condition where they are nearly as low in front as behind but this is not desirable Pekin type.

Sometimes a drake will show a rough neck, that is, the feathers on the back of the neck will be crossed or folded over showing a tendency to curl. These birds should be avoided as breeders since there is a tendency for them to produce ducks having a crest. Sometimes a green or a greenish spotted bill will be encountered. Since the bill should be a clear yellow, breeders showing this defect should be avoided particularly as they are likely to produce birds having greenish or olive colored legs. The shanks and toes should be a clear deep orange. Black sometimes occurs in the bean. This may occur in birds of either sex but is more common in the ducks than in the drakes. In the drake black in the bean disqualifies but while it is undesirable and a serious defect in the duck it does not disqualify. The color of the plumage is white or creamy white throughout. Creaminess in this variety is not a serious defect as it is in white chickens. The use, however, of yellow corn and of foods very rich in oil tends to increase the creaminess of the plumage and should not be used to excess for birds which are to be exhibited.

The Aylesbury. This breed is particularly noted for its deep keel. It differs from the Pekin in type in that it is more nearly level in body. There is a decided tendency for the Aylesbury to run too short in body which has probably come about by extreme selection for deep keel. It is well, therefore, in making the mating to select breeders with good length of body. Since the deep full breast and keel is characteristic of this breed it is necessary to avoid breeders which show any tendency toward a flat breast. As in the case of the Pekins avoid any birds which have green or olive colored bills. The back line of the Aylesbury should be straight, showing no tendency toward a slight concavity as in the Pekin. Birds showing this shape back should be avoided. As in the Pekin black on the bill or bean of the drake will disqualify and in the duck is a serious defect. The color of plumage should be white throughout and should show no tendency toward creaminess. The bill in this breed is flesh colored instead of yellow as in the Pekin. The Aylesbury is not quite as nervous a breed as the Pekin.

The Rouen. The Rouen duck is a parti-colored breed and is therefore much more difficult to secure in perfection of color and marking than is the case with the white breeds. Moreover, the dark pin feathers make the ducks more difficult to dress than in white breeds. In type these birds are very level in body and are massive, carrying a great deal of meat. Avoid birds showing a lack of length of body or depth of keel or which are too flat in breast. The back of the Rouen should have a slightly convex or arched shape from neck to tail and it is necessary to guard against birds which have a flat or a concave back. The body of the Rouen should be carried practically horizontal. The upper line of the bill should be slightly dished or concave. The white ring about the neck of the drake is an important part of the marking. This should not be too wide but should run about a quarter of an inch in width. It should be as distinct and clean cut as possible but should not quite come together in the rear. Any approach to a ring in the female is a disqualification. White in the primary or secondary wing feathers is a serious defect since it constitutes a disqualification. It must therefore be carefully avoided. White feathers in the fluff of the drake is another color defect which must be guarded against.

Breast of Drake. The farther the claret color on the breast of the drake extends down the better will be the females secured from the mating. Drakes which are deficient in the amount of claret on the breast should therefore be thrown out as breeders. A purple rump in drakes must be avoided as must black feathers over the rump as they tend to keep up too dark a body color in the female. On the other hand too bright or light a color in the male or exhibition female will produce females which are too light in color. Drakes with light olive colored bills must be avoided as these will have a tendency to produce offspring which show too much yellow in the females' bills, and clear yellow bills constitute a disqualification. In the females solid yellow bills, fawn colored breasts and absence of penciling must be avoided. Females which are dark or nearly black over the rump are good breeders as they tend to keep up the ground color of the body and tail.

The Rouen shows some tendency to fade in color. This is evidenced first on the tips of the wings. The fading will also show in the fluff of drakes. The drakes of this breed and likewise of the Gray Call and the Mallard show a peculiar behavior with respect to the color of their plumage. About June 1 the drakes moult, losing their characteristic male adult plumage and the new plumage is practically that of the female. This female plumage is retained until about October when they gradually regain their normal winter male plumage. Young Rouens of both sexes have female plumage until the last moult which occurs at about four or five months of age, when the drakes assume the adult male plumage. The sex of the young Rouens can, however, be told by the difference in the color of the bills.

Fig. 6. Upper—Rouen Drake showing summer plumage. At this season the Rouen drake assumes a plumage resembling quite closely that of the female. In the fall the drake again assumes the normal male plumage. Lower—Rouen Duck. (Photographs from the Bureau of Animal Industry, U. S. Department of Agriculture.)

The Cayuga. The Cayuga is much like the other breeds of the meat class in general type or shape of body showing good length, breadth and depth. It is a very solid duck and weighs heavier than it looks. The body carriage is slightly more upright than the Rouen but not so much so as the Pekin. The back line should be straight and any tendency toward an arched back must be avoided. It is slightly smaller than the Pekin, Aylesbury and Rouen, averaging about a pound less.

In making the mating, size is important and breeders should be selected which are up to standard weights if possible. While this breed is not kept very widely at the present time, nevertheless it is an excellent market duck, dressing out into a very plump yellow carcass in spite of its black plumage which is a disadvantage in dressing. The color should be a lustrous greenish black throughout, being somewhat brighter in the drake than in the duck. The duck is more likely to show a brownish cast of plumage, particularly as she grows older. It is hard to hold good black color with age. Moreover, white or gray is apt to occur in the breast of females. With age also a little white sometimes develops on the back of the neck, around the eyes and underneath the neck at the base of the bill. The white which occurs in breast is more likely to come in ducks and is not commonly found in the drakes. In the drakes on the other hand, there is a tendency for the white to come on the throat under the bill.

Drakes as a rule run truer in color and hold their color better than do the ducks. Where the white mottling occurs in plumage with age one need not hesitate to breed from these birds if they were of good black color as young birds. The drakes of the best color do not as a rule fade or become mottled to any great extent with age. It is necessary to guard against birds as breeders which have a rusty brown lacing on the breast and under the wings, also those which have a wing-bow laced with brown. There is a tendency for the bill of drakes, which should be black, to be too light or olive in color and this tendency increases with age. Drakes with bills of this color should be avoided as breeders. When Cayugas are first hatched the baby ducks all show a white breast.

The Call. The Call ducks are the bantams of the duck race. There is always a tendency for them to grow too large and this is especially true when they have an opportunity to eat all they want as for example when they are fed with the larger ducks. They should not be fed too liberally and should be given wheat or some other solid grain rather than any mash. If there is a good pond of water to which the Call ducks can have access they do not need to be fed much of anything.

In breeding, the smallest individuals which are suitable in other respects for breeders, should be selected in order to keep down the size and offset the tendency to breed larger in successive generations. In type the Calls are practically miniature Pekins except that they should have a very short, rather broad head and bill. The broad flat and short bill and the round short head give the head an appearance which is often described by the term "button headed". In this breed avoid birds which show arched backs. The body should have what is known as a flatiron shape, that is, should be broad at the shoulders and taper toward the tail. Too deep keels and narrow shoulders should be avoided as should also too long bills. Call ducks, together with East Indias and Mallards should have their wings clipped or be pinioned, that is, have the first joint of one wing cut off, to prevent them from flying away.

The Gray Call. The plumage of the Gray Call is practically that of the Rouen although they are not quite as good in color as a breed. There is more of a tendency for some of the birds to run to dark and others, especially the males, to run too light in color. While they are likely to be well penciled the shade of color is apt to be wrong. White in the flights and under the wings must be guarded against as must also absence of ribbon or wing bar in females. The color of the plumage is likely to fade with age but after the birds moult and secure their new plumage, the color is usually higher again. In general the same color characteristics hold true as with the Rouen and the same defects must be guarded against.

The White Call. This variety is, both in type and color, practically a miniature Pekin except for the short, rather broad head and bill. They breed very true in color and should be free from creaminess. The same general defects must be watched for and avoided as in the Pekin.

Fig. 9. Upper—White Call Duck. Lower—White Call Drake. (Photographs from the Bureau of Animal Industry, U. S. Department of Agriculture.)

The Black East India. This is a black breed which is small in size being a bantam duck like the Call. As a matter of fact it is a miniature Cayuga. The color should be black throughout and the same color characteristics hold true as in the case of the Cayuga. The same color defects must therefore be guarded against, the worst one being white in the breast of females especially. Avoid breeding from a drake with a black bill as in this respect the breed differs from the Cayuga since the bill of the duck should be black but that of the drake should be very dark green. Purple barring must be carefully selected against.

The Muscovy. This breed differs in certain respects very markedly from the other standard breeds of ducks. They are long and broad in body which is carried in a horizontal position but are not so deep in keel as the Pekin, Aylesbury or Rouen. The longest bodied young ducks will make the largest individuals. The head should have feathers on the top which can be elevated at will to form a crest. Guard against breeders having smooth heads, or in other words, lacking a crest. The face is covered with corrugations or caruncles and should be red in color. At the base of the upper bill there is a sort of knob-like formation in the drake which serves as one of the distinguishing characteristics between the duck and drake of this breed. The more prominent the knob and the more wrinkled or corrugated the face the better is the specimen in this respect. The wings are long and strong and these birds fly very well. They will also climb fences. The drakes are quite pugnacious and fight one another badly at times. They are especially pugnacious when they have young.

This breed of ducks will often roost on roosts like chickens or in the trees or on the barn. They do not quack like other ducks and unlike other domesticated breeds which moult two or three times a year, they moult only once, taking longer to do so, usually about 90 days, although the female may complete her moult a little sooner. The period of incubation for Muscovy eggs is longer, being from 33 to 35 days as compared to 28 days for other breeds. In size the male and female differ considerably as will be seen from the standard weights given (See Page 14), the male being considerably larger. These ducks lay well, the fertility runs good, the eggs hatch well, and the little ducks are hardy and easily raised. They are a broody breed. The ducks will make their nests and hatch out their eggs if allowed to do so and are excellent mothers. Sometimes they will fly up and make their nests in a hollow tree. A Muscovy duck can cover properly about 20 eggs. In spite of the fact that they fly well they are easily domesticated. It takes about two years for the males of this breed to fully mature although the ducks get their full size when one year of age. The Muscovy is perhaps the best general purpose breed for a farm flock.

The extent and intensity of the red of the face increases up to maturity and the redder the face the better. The plumage of the Muscovy is not as downy or oily as other breeds, the feathers being harder. For this reason the birds are more apt to become water soaked and to drown as a result when they have not been accustomed to water in which to swim. This is especially true of the drakes on account of their large size and long wing feathers. Muscovy ducks dress well, having a rich yellow skin, and therefore make a good market duck, although the difference in size of the duck and drake and the dark pin feathers of the Colored variety are disadvantages from a market standpoint. Select against breeders which run small in size as there is more or less of a tendency for this breed to decrease in size. The Muscovy is long lived, specimens having been known to breed until they were eight or ten years of age.

The Colored Muscovy. Although the standard calls for more or less white in different sections of this variety, as a matter of fact breeders desire to get the birds as dark as possible except for a very small patch of white on the breast and a small patch of white on the center of the wing. Indeed, birds without the white on the breast and with very little on the wing are valuable breeders since there is a tendency for too much white to occur in the plumage. Occasionally all black birds occur and these can be used to advantage in breeding when there is a tendency toward too much white in plumage. Plumage more than half white is a disqualification. The dark plumage birds such as are wanted are very likely to show considerable black or gypsy color in the face which should be a good red. This must be selected against insofar as possible. The nearly black or the darkest birds are quite likely to show some white or grizzling on the head. Grizzled or brownish penciled feathers sometimes occur in various parts of the plumage and must of course be guarded against as the markings should be distinctly black and white. The baby ducks of this variety are quite apt to show considerable white although the best of them come yellowish black. This variety tends to run a little larger in size than the white variety although the standard weights are the same for both. Dun or chocolate colored ducks sometimes come from Colored Muscovies while Blue Muscovies can be produced by crossing the Colored and the white varieties.

The White Muscovy. This variety should have pure white plumage throughout. Young Muscovies of both sexes often have a patch of black on top of the head up to the time they moult at maturity. Since black disqualifies it is impossible to show young ducks in this condition but these black feathers usually come in white after the moult and such birds need not therefore be discarded as breeders. When it is desired to show young White Muscovies which have black on the head it is customary to pluck these black feathers a sufficient time before the show so that the white feathers which come in their place will have time to grow out. There is little or no trouble with black or gypsy face in this variety.

The Blue Swedish. In type and size this breed is about the same as the Cayuga although perhaps slightly more upstanding. In selecting the mating it is important to use birds which are close to standard weight as there is somewhat of a tendency for the size to be too small. As its name indicates the color is largely blue except for a white heart-shaped patch or bib which should be present on the breast. Sometimes this white extends along the underside of the body from the under-bill almost to the vent. Such birds are undesirable as breeders since they show too much white. On the other hand birds lacking a prominent white bib must also be avoided. Two of the flight feathers should be white and birds lacking these must be avoided. Guard against any red, gray or black in any part of the plumage. Sometimes, however, birds having more or less black throughout the plumage are used as breeders for the purpose of strengthening the blue color. Avoid any tendency toward a ribbon on the wing-bow and also birds that are too light, ashy or washed out in the blue color.

Sometimes birds show lines of white feathers around the eyes and over the head and these should be selected against as breeders as they are likely to cause white splashing in the plumage. Yellow or greenish bills must likewise be avoided since the first of these is a disqualification. In general this variety in breeding behaves insofar as color is concerned, very much like the Blue Andalusian chicken.[3] The young ducks when hatched are yellow or creamy blue and from blue matings there are also produced black and white ducklings. As in other colored breeds and varieties, the dark pin feathers are somewhat of a disadvantage from a market standpoint.

[3] For a detailed discussion of the behaviour of the Blue Andalusian in breeding, the reader is referred to "The Mating and Breeding of Poultry" by Harry M. Lamon and Rob R. Slocum, published by the Orange Judd Publishing Company, New York City.

Fig. 12. Blue Swedish duck showing white flight feathers. The Standard calls for only two white flights, but there is a decided tendency as shown here for more flights to be white. (Photograph from the Bureau of Animal Industry, U. S. Department of Agriculture.)

The Crested White. Although not so large, this breed is much like the Pekin but with body carried more nearly horizontal and with a crest on the head. The type varies considerably however, the principal selection practiced having been for crest. The plumage is white in color throughout. What is desired in the crest is to have as large a one as possible, round and perfect in form, and set squarely on the head. Not infrequently crooked crests occur and also double or split crests, that is to say, where the crest is parted or divided. In some cases the crests may even come treble, that is, split into three parts. Entire absence of crest is by no means uncommon. In fact, it is considered a pretty good proportion if one half of the ducks hatched have crests although the matings vary considerably in this, occasionally one producing practically 100% of the offspring with crests. Avoid as breeders birds with small crests, lopped crests, split crests or showing an absence of crest. Avoid also breeders showing mottled or green bills in females and black bean in the bill of drakes.

The Buff. In type this breed is similar to the Swedish. As will be seen from the standard weights it is one of the medium sized breeds and makes a very nice market bird as it dresses out into a nice round fat carcass and is a good layer. In color the birds of both sexes should be as uniform a buff as possible except that the head and upper part of the neck in the drake should be seal brown when in full plumage. Color defects which are likely to be encountered and which should be avoided are the tendency for the head of the drake to run to a chestnut color and for his neck to be too light or faded out in color. Sometimes the head of the drake runs too dark in color approaching a greenish black like the head of the Rouen. This is of course undesirable. The wings of both sexes are apt to run to light or even in some cases, pure white flights. Blue wing bars are sometimes shown and these must be carefully avoided. Penciling such as is found in the Fawn and White Runner sometimes occurs and since it is a serious defect must be rigidly guarded against. Any tendency toward a white bib or a white ring around the neck of both sexes must likewise be avoided. Greenish or mottled bills must be avoided in ducks which are to be used as breeders. Not much trouble is experienced in the bill of drakes which as a rule comes good. Any blue cast in the feathers on the rump and back of both sexes must be selected against. As a rule the females of this breed tend to be better colored than the males. At certain periods of the moult the head coloring of the drakes becomes a good buff color and later when the moult is complete, it changes to a copper color. When hatched the ducklings are a creamy yellow.

The Runner. The type of this breed is quite different from that of the other breed of ducks and type is very important. The Runner wants to be decidedly upstanding and to be very reachy. It should have very slim slender lines. The neck should be straight and the head should be carried at right angles to the neck. The bill should be perfectly straight on top and on a line with the skull showing absolutely no tendency to be dished. The legs of this breed are longer than those of other ducks and this accounts for the fact that they run rather than waddle when they move about. It is from this fact that they get their name. They are very active and are troublesome about crawling through fences. They are good layers and non-sitters and they have often been called the Leghorns of the duck family. It must be remembered, however, that while they have the inherent ability to lay as well as hens they will do this only when they receive proper feed and care. It is quite useless to expect a high egg yield from them when they are carelessly fed and improperly housed and cared for. Avoid as breeders ducks of both sexes that are too heavy behind, or in other words, are too heavy-bottomed. Avoid birds which are too short in legs. Avoid crooked or sharp backs. Round heads must likewise be avoided.

The Fawn and White Runner. In this variety the markings must be very distinct and definite. There is a tendency which must be avoided for the head to run to black instead of chestnut, especially in males. It is likewise necessary to avoid females which tend to show penciling on the sides of the breast or on the wing-bows. These defects are apt to be associated with colored flight feathers which is also a defect to be avoided. Guard against too much fawn extending up the neck from the body to the head as the neck should be white in color. Too dark tail coverts approaching a greenish black sometimes occur and are undesirable. In type this variety will not average quite as good as the White.

The White Runner. This variety is best in type and it likewise runs good in color which should be white throughout. Sometimes foreign color will be shown in the back of females and this of course must be avoided. Also avoid birds as breeders with green or mottled bills.

Fig. 14. Penciled Runner Drake on left and White Runner Drake on right. (Photographs from the Bureau of Animal Industry, U. S. Department of Agriculture.)

The Penciled Runner. In type this variety runs about the same as the Fawn and White. The color combination is rather difficult to breed as it is hard to get the good penciling desired in the female together with the white markings. In general, in breeding this variety there is a tendency to pay more attention to type than to color. The penciling is like that of the Rouen but lighter in color consisting of a brown penciling on a fawn colored ground. Avoid any grayish stippling on the breast of the drake and also on the wing-bows. These defects are likely to be associated with colored flights which are undesirable. The colored portion of the head of the drake is darker than that of the duck in this variety. Avoid lack of white on the neck in both sexes and avoid females which are lacking in penciling.

Preparing Ducks for the Show. Aside from selecting the individuals which most nearly approach the standard requirements there is very little which can be done in the way of preparing the birds for the show as these fowls are practically self-prepared. For a period of at least a week or ten days before they are shipped to the show those intended for exhibition should be given access to a grass range and also if possible to running water. The grass range will keep them in good condition and the running water will allow them to clean themselves. Any broken feathers should be plucked at least six weeks before the birds are to be shown in order to allow the feathers time enough to grow out again. It must be remembered that most ducks after getting in a good condition of flesh do not tend to hold this for a very long period but soon grow thinner again and will not take on fat the second time for some little period.

Often there will be a difference in weight as high as 3 pounds when a duck is in good condition and after it has thinned. In order to have the ducks in top form, therefore, it is necessary to bring them up to flesh at the proper time. In order to bring ducks which are to be exhibited up to standard weight, they should be fed twice daily, for at least 10 days before shipping, a grain mixture consisting of one part corn and two parts oats. Give them all they will eat of this mixture. With Runners and the small breeds of ducks there is a danger of their putting on too much weight if corn is used in the ration and it is therefore best to give them oats alone. When the birds are shipped to the show they are quite likely to get their plumage soiled during the journey. When this occurs fill a barrel about half full of water. Then as the ducks are taken out of the shipping coops take three of them at a time, put them in the barrel and cover it over, leaving them for a few minutes. When they are taken out they will usually be clean.
