I have a pretty young flock , 8 pullets, and 1 cockerel. just to give you some info on their living conditions, the coop is 6' x 20', plenty of roosts, and 6 nest boxes. the run is 20' x 35', so they have PLENTY of room for just 9 birds. I know that my cockerel is young, and full of hormones, he goes after the pullets very often. there is 1 pullet in particular that he likes a lot... and her back can prove it to you... her feathers are all tore up on her back, the others have a frayed feather here and there, but Scruffys back is looking horrible. Is there anything I can do to help? she is not "bare" yet... But if he keeps after her like he is, it won't be long before she has no feathers on her back.
