I just got home after being gone for two days. When I went out to check on my girls, one of my white rocks had a bare bottom. I know she definitely had feathers there Friday afternoon when I went out last, bc this was very noticeable from a distance. There was a bit of poop stuck to some of the feathers but she wasn't clogged up. She seems to have plumped up in the last two days too. She seems considerably larger than her sisters now. They are 24 weeks. At this point I'm not 100% sure if she is laying or not but I don't THINK so. Her feathers are damp in the picture from where I rinsed the poop off.
Do you think she may be sick? Or that possibly one of the other chickens plucked the feathers out?
This is her:
And these are her sisters
