One of my chicks (Buff Orphingon) has a wet butt and I cannot figure out why. Sometimes it is dry but you can tell it was wet and dried on the feathers. I have cleaned the butt and in 2 or less days has a wet butt or there is evidence of being wet again. I have watched the chick poop and there is nothing wrong with her poop or does not appear to have a difficult time pooping. Can you please tell me what could be wrong??? There is also no feathers around the wet butt and from time to time she appears to be picking at her bottom. The other chicks do not pick on her or pull her feathers. It is also not pasty butt and the butt is not dirty. Please help me!
