I've got 6 pullets, about 9 months old. Recently, I noticed that all of them except one were starting to look scruffy around their tail feathers. I've observed them quite a bit and deduced that the one without any feather damage is a big bully - she's pecking all of them. There's a few with bald spots. One has been a little bloody by her tail the past few days. I've put blue kote on her wounds and she seems to be healthy otherwise. The others are still bald by their tails, but I've started giving them some diversions and their feather damage doesn't seem to be getting much worse. So, the question is, should I separate the bully hen from the flock for a few days, or should I separate the hen who has been getting bloody to let her regrow some feathers? Or should I separate both of them from the other four? I don't have a lot of options for separate pens, but I could probable work something out for both of them. Thanks!
