I have a RR that is about 9 months old and I just noticed that all of her bottom feathers are missing! She doesn't appear to be in any distress and the rest of the flock is fine (10 others, all girls). It doesn't look raw or anything like that. There may be one small area that is slightly red but that is it. Any ideas on what it is and how I can help her get her bottom feathers back?? As always, thank you for any suggestions you can offer.
