So I currently have 4 bantam chickens who have a coop and a run, though they spend a majority of their time free range in the garden. I only leave them shut in their run if it is bad weather or no one is around. I would like to introduce 2 ducks (possibly Campbells?) but am wondering if they would sleep in the chickens coop, or should they have their own coop for nights and a fenced off section to leave them in when I am not around? I know that ducks will need some water so would have a little pond/paddling pool in the garden for them (away from the chickens coop so they wont get upset with getting wet and muddy!) but would they be ok out and about in the garden together during the day? Might seem a silly question but if I got the ducks their own house would they go in there, or would the chickens and the ducks get confused whose house was whose? Any advise would be much appreciated!
