Ducks are a lot hardier than a chicken. No, I don't think the meat is fatty or greasy. I really like it! And the eggs are good for baking. As for breeds, I can't give much advice because I have Rouens. They are nice, but the hen really likes to wander. Just do some research- all depends on the size of the yard and housing, and whether you want meat, eggs, or a dual purpose bird. But they will messy with water, that's for sure. And yes, I notice my 3 put holes into the ground with their bills too! I thought they were drilling for bugs
