Semois Ducks are small ducks, usually just raised to be a pond ornamental.
They have white feathers with thin necks, yellow beaks, and light orange shanks.
The females lay greenish-shelled eggs.
The birds will weigh 2.75 to 3.3 pounds (1.25 to 1.5 kg.)
The Semois Duck breed emerged perhaps at the start of the 1900s in the southern part of Belgium.
It was not really described until 1971, in the book Study on Chickens and Waterfowl by Etienne Brandt in 1971.
