Hi everyone. This is my first flock of chickens. I have 1 Barred rock, 2 buff orpingtons and 2 golden sexlinks. They are 7 months old. We noticed about 2 weeks ago that the smaller sexlink was separating herself from the rest. She roams by herself and rarely will join the others. Last week they all got fowl pox but I noticed today that it looks like they are pecking at her comb and pox marks. I think they are bullying her. She is smaller than the rest but otherwise seems healthy. We also can't tell who is laying. We consistently get 3 eggs. So it seems like 2 might not be laying. Any advice on why or what to do about the pecking and bullying?
