i forgot to say that all my chix and ducks stay together in the coop easily. The ducks are a bit bossy, but they are also alert. If something wicked comes in the night, they wake up the turkeys in the trees and they sound the alarm, so the chickens wake up. The coop is away from any water, though, so it doesn't get all muddy inside. We built a small duck house so we could separate them if we wanted to. It is low, like a dog house, and the chickens don't like it because there is no high perch.
