We have 1 original, 3 new hens (unfriendly given to us when we lost 2 to hawks), and 4 new wonderfully friendly girls picked up Sunday. Right now they're each in a coop (2) and don't mingle while free ranging. They haven't even really noticed each other. Is this ok? I don't care but should they be integrated? They forage on 1 acre and their coops are <10 feet from each other.
