We have 5 two-month-old Welsh Harlequin ducks (1 male, 4 female) in one room of the barn with an outside pen and 40 some mixed flock chickens in the room right next to them. There is a screen door between them so they are used to each other that way. Chickens have always been free-range but we've lost 3 to a raccoon lately so I've kept them inside and they are not happy. Until we figure out making a large outdoor pen for the chickens, I'd like to open the screen door between ducks and chickens. That would give the chickens access to an outdoor pen and a new area for the ducks. I'm thinking to open the door late afternoon so they see each other "in person" when they are all more mellow. Does this sound like it would work? I don't want anyone to get hurt!
