I do have a maternity/isolation coop and run, but do not have a spare coop. It’s been absolutely fascinating to watch them! They split on their own and I’ve very much enjoyed learning from the process. A majority of them sleep in a tree, only 2 hens sleep in their coop, but the rest sleep together in the same tree. I thought once they split in to two flocks, roosting would also be divided, but the roosters come together for that part of the day without any quarreling. I’m a little surprised that they’ve turned out so “feral” but I’ve never raised them to be restricted. Im not sure how to find your coop page? Could you please share it with me?
