Can anybody give me suggestions about why one hen who was/is my sweetie is being rejected by my new cockrel/rooster and now one of the other hens picks on her also. I just noticed that she has a spot of blood on her comb. She started broodiness but will wander out and try and join the flock but the roo and/or the hen will chase her back in the coop. I have an 8x10 shed for coop and an 8x12 fully fenced run. She stopped laying. This has been going on for a few days. When I got the rooster I noticed he was sick. I isolated him and took him to avian vet. A couple of antibiotic shots and vetrx did the trick. I am looking forward to them all getting along. Is this an unrealistic goal?
