The majority of people have the impression that water to bathe in is essential to secure fertility in duck eggs, but it is a great mistake. My ducks never see water, the year round, except to drink. They are confined in yards 24x100 feet, some forty in each yard, twenty-four feet being the size of the pens inside of the breeding house. They are confined in these yards for nine months, or till August 1, when they are removed in order that the land may be disinfected. This is done by plowing and growing a crop of barley or rye, when the land is ready for the ducks again.
