I have one chick, I call her "Little Wing" because shes smaller than the rest of the flock (I think she may be a week younger than the rest, but I'm not sure because I got them all at the same time). All the girls are getting their adult feathers in, and they're coming in beautifully. Little Wing's feathers are coming in as well, just slower than the rest. All the girls 'chick' feathers are starting to fly around my garage as their new ones come in. With that being said, I haven't noticed any spots on the girls where there are no feathers at all. Little Wing has a spot around her toosh and tail feathers where its just bare. It doesn't look to be red or irritated or any sign of blood and it doesn't seem to bother her at all. Is this common? I'm going to watch her like a hawk for a while to make sure it doesn't start to bother her. I don't see it with any of my other girls.
