Duck...almost all domestic ducks are descended from a wild breed called a mallard.  The males have brown bodies with a green head and a white stripe around their neck.  Like most birds, the female has much duller coloring.

Here at the farm we have Pekins.  They are the most common type of duck in America. It is bred in one variety, white; and a creamy white plumage and orange  feet are desired. The bill is rich yellow in color. Pekin ducks should weigh not less than, adult drake (the male), 9 lbs adult duck (the female), 8 lbs. The correct shape is of a long, broad, deep and full-breasted type, to carry an abundance of meat. The Pekin breed is of Chinese origin, a country in which consumes a lot of ducks. The first Pekins were imported to the United States about 1873 for meat production.  They adapt very easily to different climates, and are found throughout the United States.
