I've had chickens for a few years now and I've recently been contemplating either adding to or replacing the chickens with ducks. I have a smallish backyard and keep the chickens in a chicken tractor. We live in a neighborhood with a nice sized lake that we live right next to.. My question is; Would it be practical to think that I could allow the ducks to have free range of the lake and come home to lay and sleep? They would have about a 100 yard walk between "home" and the lake. Would it be more likely that they would just live full time on the lake and I'd never get any eggs from them? There are other ducks on the lake, presumably belonging to folks who live directly on the lake. Would I be very graciously providing them with extra ducks by letting mine free range? Thanks for the input.
