I have 3 one year old hens just recently noticed 2 want to sleep on roof of coop when i went out to close the coop. I put them in coop and stayed around to see whats up and the one hen was pecking others as they fought for certain spot on roosting bar. In the winter I noticed the bully slept spot furthest from opening and now she wants right by opening but other that had that spot still wants that spot. I took boards out so they can all see out and be airy but that didn't help. Not sure if shoud get bigger roosting area, current one is almost 3 feet long. Bully is new hampshire red other two are americanas. Almost to point i may need to get rid of her. Thanks for information
