I just got chicks this week, all are doing well. I have one girl, Kevin, who has a poopy behind all the time. I have to clean her hiney at least once or twice a day. She is the only one having issues like this. She is a Silkie so I don't know if that has anything to do with it. The rest of them all have butts that are just as fuzzy and they manage to stay clean. What's going on? Who cleans their rears in the wild?
