We have a large coop for 3 hens. We just introduced the new hen 2 days ago and one of the hens is getting progressively more aggressive. Picking her, keeping her from roosting with her and keeping her out of the hen house. There is plenty of room for them to have their own space. I just do not know if we should separate them? When is aggressive too aggressive? I'd like to just see how it goes and hope they get along better soon.
