So, I know what chickens need re: housing. Are there any major differences for ducks? I know that ducks need to be able to dunk their heads to clean their nares, so nipple waterers are out (or, at least, I can't solely have nipple waterers), and medicated feed is out (not that I plan to buy medicated chick feed if there is any other option)--and if I haven't any choice, add niacin somehow. What kind of sleeping arrangements? Do ducks perch, or snuggle on the floor? (I'm getting calls, and will probably look around for muscovy.) I know I could go to the duck forum and research myself, but I already know the duck Ponders know what they are talking about
