We are in the process of integrating 4 almost 5 month olds (2 Buff Oprs and 2 SLW) to our existing flock of 5. They spent the first month in their own coop and run with the older birds looking at them. Then they spent a couple of weeks free ranging together but sleeping separately. Now we are trying to have them sleep in the same coop. The first night the new birds spent huddled on the floor of the coop at the top of the ramp by the pop door which we left open that night (it's usually closed). The 2nd night the new birds were again huddled on the floor of the coop, so we physically put them up on the roost. 3rd night same thing. Tonight when we tried to put them up on the roost one of the bigger birds that was close by pecked the head of the younger bird. She didn't move away, just put her head way down. The upshot is that one new bird is on the roost away from the bully and the other 3 are huddled on the floor of the coop in a corner. One thought we had was to make the bully sleep in the extra coop by herself for a night or 2 and see if that makes a difference. Are we interfering too much? Should we continue to put them up on the roost and let them handle a little head peck? Or should we let them sleep where they want even if it is on the floor of the coop? Thoughts?
