Which duck breed is best for small and backyard poultry flocks?

Another bird widely kept in domestication is the Muscovy. Although often referred to as a duck, the Muscovy actually is a different species. It is hard to categorize Muscovies—they have a body like a duck; they nest, attack predators, and hiss like a goose; they roost like a chicken; and they have a plump breast like a turkey. The male Muscovy has characteristic fleshy growths around the eyes called caruncles. It is believed that Muscovies originated from South America. They are still found in the wild in the warm regions of that continent and are raised domestically throughout the world. The Muscovy is called the Barbary duck in southern Europe and North Africa and the Brazilian duck in Brazil. In the Guineas, it is known as the guinea duck or turkish duck because of the caruncles on its face. The Spanish call it the Pato, as do some handlers in the United States. The Muscovy also is known as the Cairo duck, Indian duck, musk duck, and turkey duck.
