I have a fairly new flock of Buckeyes. When I first got them, I put them in the same coop as my old hens. The old girls didn't let them up on the roost at night so they started sleeping on the floor under the nest boxes. Now I have moved them to their own coop, and they all (4 hens, 1 rooster) still sleep on the floor, right in front of the door. Even though we built them a very nice roost and nest boxes. In fact they are even laying their eggs on the floor instead of the boxes. Is this just because of how they were forced to sleep on the floor at first, or is this just common for this breed?
