I have 20 one year old hens. I did have 5 roosters in with them. Three week ago I was finally able to find a home for 4 of them and only have one in there now. I think that was way too many roosters and that accounted for their loss of feathers, Many of them have most of there backs exposed. That brings me to the next problem. These exposed backs are getting very sunburned. One is especially bad. I have removed her from the coop during the day and put her in a cage that I have in the barn. At night I put her back in the coop to roost. Today when I was out there I noticed that all the hens had her down and were pecking her. I took her out right away and put her in the cage. Can anyone tell me what to do about the sunburn until the feathers come in and are the hens picking on her because I removed her from the group for the daytime? I feel at a loss.
