Hi all, I should know this by now but I am known for stressing over pointless things. I am trying to introduce 5, 6-7 week old chicks into my big chicken coop. There is normally 12 chickens in the coop, 11 hens and 1 rooster but right now its just 4 hens. The rooster and other hens will back by Sunday. The hens are pecking the chicks even when the chicks are being really nice. Is that normal? And will my Rooster hurt them because he is so big and they are so tiny?
