I had 7 young laying hens, and about a month ago one was pecked to death. A few weeks later I noticed that a few of the others had bloody wounds like the one that died, and decided to isolate them. While they were isolated, I let them free-range with the others for about an hour every other day, and they all got along fine. I recently decided to put the isolated hens back into the coop with the others, so I let them all free-range first. I noticed that a few of them started fighting, and I isolated the one that was picking most fights and the one who was getting most picked on (the skinniest- I guess that's why she's bullied). While free-ranging, it seemed that the 4 left over were fine, but later in the coop tussled a little. The hens are now in two groups- the formally-hurt ones and the others, and they get along within their groups, but not with each other. I have the bullies in isolation now, because I don't know what to do. I can't have them fighting with and killing the formally-hurt ones. Any ideas? I may be able to find a home for one of the groups if I have to.
