Well to avoid ducky confusion he should be with another duck, they are very social creatures. Plus if it turns out to be a male and eventually tries to mate your female chicken he could seriously harm her as ducks have different organs than chickens do. If you want, metzer farms will sell you 2 ducklings (the minimum is 2) to keep it company. Or you could check your local craigslist. You can feed them chick food though it should be non-medicated (others disagree with me but thats my opinion) because ducks eat more than chickens and can end up getting too much medication. They don't have to have swim water, until they have adult feathers they shouldn't ever be unsupervised swimming, but swimming does make them happy. Ducks are VERY messy, much messier than chickens. They will play in their water and fling it all over. They do need water deep enough to be able to clean their sinuses though, otherwise they can get clogged. Chances are if yours is a wild duck, it's a mallard, so cute! Best of luck! Oh, also I add niacin to the water for my ducks to help avoid leg issues.
