Shortly after the loss of one of our hens, we noticed that our rooster and a few of the other hens were picking on one of our leghorns. They had actually pecked her comb almost completely off! We seperated the hen to treat her wounds and let her recover. A few days later we returned her to the coop, at night after the others had roosted down, without any major issue. Strange thing is they roost with her every night but during the day our rooster keeps her segregated from the rest of the flock. If he chases her, the others join in. She seems so lonely. Today we tried seperating the rooster to see if the other hens would let her rejoin the group if he wasn't starting up problems, but she now just runs away when any of the hens come near her even if they aren't being aggressive... Help?
