Hi! we have six hens/pullets, and a younger egg laying barred rock is getting pecked like crazy! We thought the integration of the chickens was going OK(ish) until the three hens (mostly just 2) started picking on (more than usual/chasing a bit) JUST the one barred rock. she is the oldest of the three new ones and is very sweet. She does a submission squat to them a LOT and that is causing her a lot of pain, as they stand on her and peck. It gets better and worse, for example there hasn't been any new blood lately, but i feel REALLY bad for her. She has a scab AND Missing feathers on her head! hey are drawing her away from the food and water, and she has a hard time running away from them in the smallish coop, so she camps out in the nesting boxes. Is there anyway to help? thanks P.S she seems kinda small for a barred rock...
