Ducklings of a domestic duck
The domestic duck or domestic mallard is a subspecies of mallard that has been domesticated by humans and raised for meat, eggs, and down feathers. Almost all varieties of domesticated ducks, apart from the domestic Muscovy duck, are descended from the mallard.
Ducks can be kept free range, in cages, in barns, or in batteries. Ducks enjoy access to swimming water, but do not require it to survive. They should be fed a grain and insect diet.
The females of many breeds of domestic ducks are unreliable at sitting their eggs and raising their young. Exceptions include the Rouen duck and especially the Muscovy duck. It has been a custom on farms for centuries to put duck eggs under broody hens for hatching.
Once the duckling grows its own feathers, it produces preen oil from the sebaceous gland near the base of its tail.
Ducks are also kept for their ornamental value. Breeds have been developed with crests and tufts or striking plumage, for exhibition in competitions.
