Hi! Looking for some advice. I have 4 chickens: two older pullets about four months old and two younger pullets about two months old. I integrated the younger ones and I thought all was well. But then, they had one bad day while I was on vacation where they didn’t get let out (caretaker mix up) and got bored, and one older girl had her tail pulled out and one younger girl had her chest feathers pulled out. I think the culprit is the other younger girl. The chest feather pulled out one is growing feathers back ok, though I notice new bald spots occasionally. The one with the tail issue though isn’t healing, and it keeps getting messed with and bleeding occasionally. I want her to be able to heal and grow her tail back so I am going to set up another coop and separate them. Just wondering who should get to stay in the original coop? Does it have some sort of affect on the pecking order to separate them?
