I wrote in earlier this month when one of my hens had a raw open wound on her back. We cleaned it applied antibiotic and it appeared to heal. We never really figured out what caused it, but it didn't appear to be a predator-no punctures or bites. Now I found this same hen in even worse condition. I think now it is the other hens pecking at her. This time I didn't think she would make it. Her skin and feathers were gone in an area of 4 inches wide. So far she's OK, I've isolated her again. I've never witnessed one of them pecking each other, just some occasional posturing over food, etc. I've read all the reasons this might happen and it doesn't seem they apply. The coop is small, but they free range all day, there has been no change in the flock (they grew up together), they get commercial feed in addition to sunflower seed and kitchen scraps for treats (no meat though, we're vegetarians), no stressors I can identify. Any ideas??? Someone recommended giving them meat scraps. Has anyone had any success with doing that?
