We recently added some new chicks to the coop, after about a month of "see don't touch". There is still some bullying going on, but for the most part, pecking order has been established, and everybody is getting along ok. The problem is a bedtime. We often peek into the coop windows at bedtime. The first night, the chicks (they are almost 4 months old), tried to sleep on the roosting bars. They had a hard time, and only half did, the rest were in a corner on the floor. I thought they were just adjusting. For the last week, they are all now sleeping on the floor. A few days ago, they all headed into the coop early, before any of the older ones went to bed! I thought it was so funny, they were all on the roost, ready to sleep. I decided to watch, and one of my older hens came in, and pecked each one of them until they were all on the floor again, which is where they are now sleeping! Help! How to do I the older girls to accept the new girls and allow them to roost? And how bad is it that they have to sleep on the floor of the coop? The coop is sturdy and clean and secure from predators, so that is not a problem , I just worry that they obviously WANT to roost, and are not being allowed to.
