There is a lot of information in this site and the internet about muscovies. They are a South American tree duck unrelated to farm duck breeds that are Mallard based. If you breed muscovies with other ducks the offspring are infertile mules. Muscovies are not as eager to swim as other breeds and are more of a shore bird. In the wild they lay their eggs in hollows in trees. They also fly way better than other ducks and can climb well with the clawed feet. You have to be careful when handling them because of the razor sharp claws. Even little ducklings can get you and it is like being clawed by a cat. Nevertheless, they have great personalities and seem way smarter than other ducks. Here's Hunk the head drake: And Brownie, the first hen to hatch a surprise batch of ducklings. I didn't think the eggs were fertile . Both are very friendly and wag their tails when they see me coming to visit their pen. They did well this winter outside in their small house with an enclosed run. A moderately sized rubber water pan kept them happy and was easy to break the ice out of. I feed them 16% chicken layer pellets. The ducklings are big enough to process at 8-10 weeks and the males are huge by 3-4 months. When the babies were small I had to go away for a week for work and when I got home the babies in the picture had doubled in size.
