I have a buff orphington that has been sick for a while now. I noticed she was sick over a month ago, took her to the vet. She got better so I put her back with the flock and she did well for about a week. Took her back to the vet and got meds, she had lost 2 pounds. Basically coccidia was to blame. She has been in the basement in the recovery room for about 2.5 weeks. Today I decide its warm enough to let he hang out with the flock. She looks visibly excited when I take her out there but as soon as I let her in the pen the other two hens start to pec her in the face and neck. I stopped them and watched for a while and they started up with the same stuff. So I had to take the buff back out and put her in the basement... she looks very depressed down there. So what can I do?
