I just noticed that one of my 11 week old Buff Orpington pullets was allowing her neighbors on either side to peck at her ear area. She stood very still and let it continue until I interrupted. Not bloody (yet) but definitely sore looking on both sides. First photo is a pic of her darker ear area as well as the red area below. Second photo is a comparison to her healthy counterpart. I'm at a loss as to what this might mean. No cockerels in the mix. Mites? I have VetericynVF that I can apply if need be. I don't want the situation to escalate over night. Photo below is of healthy counter part with normal ear area for comparison. ETA, all pullets are same age from original hatch group.
