I got them as ducklings and thought topknot was a girl,named her Gladys, Know I know it is a drake, so name is TopKnot, or occassionally William. The other black one I was sure Swedish, and thought it was a boy, named him Swede. Now changed that to Sweedie, as she is laying eggs. But Grey ones. Seem to be getting darker as she grows. She has a white chest, which is not common to cayuga's. Here are a few pictures. Taken today at 6 months old. Anybody have a clue on the breed? The brown ducks are Khaki Campbells, and I have one Buff Orpenington. But what are these 2 dark ones. I included a picture of Sweedie's eggs next to 2 white duck eggs.
