Depends on how old they are. Without a mother, chicks are sometimes very slow to learn to roost. You may hafta round them up and put them on the roost several times to drive it home. Just plan on being there at dark for a week or so. Good that your bantams are docile. It's the hens you hafta watch. The cock should be fine with them.......PopThanks. The brooder box we have is large and one complete side is wire. We planned to put them flush with the run for a while so they could socialize through the fence. My Bantams are very docile birds including the rooster. Hope it goes well. Once they are all together do the new ones usually follow the leader to roost in the hen house at night? Or will I have to encourage that?
