I have got a black Sussex broody hen which shares an ark with 3 other chickens. However she is nesting in that ark but the other chickens are pestering her as they want to lay their eggs in the occupied nest. I have another spare coop should I move her into the other coop or will that stress her out? I was going to move the other chickens into the spare coop but it is only suitable for 1-2 chickens.
