This isn't an emergency yet, judging by how she is still bossy and eating like a horse, but one of the Taichou Twins (7 mo old Light Brahmas, alike as two peas in a pod) has a pretty poopy butt. She is eating and drinking with relish, runs over when I throw out scratch, acting totally normal, but the poop on her butt is black/dark brown. It's not just pieces of poo, it looks like somebody smeared it. (So gross) It is pretty cold winter here, so not everyone is laying yet. Today, however, is unseasonable warm. Is this something I need to take care of with a butt bath, or let it go? My chickens are friendly enough, but do not particularly enjoy being petted, and definitely do not like being picked up. Will a bath stress her out, or is it imperative that the poop come off? Here is the best poop butt picture I could get without her knowing the paparazzi were stalking her.

Normal? Bath worthy?
