Me and my husband purchased 3 ducks bout a week ago. We've had chickens little over a year but we've never dealt with ducks before. We have 1 khaki campbell and 2 cayugas. We were wondering if anyone could tell us if its ok to keep ducks and chickens together in same pen or wod it be better to have their own pen separate? Do ducks come home to roost like chickens or are they different?
