So one of my broody hens did not poop outside of the nest box the entire time she was sitting on the eggs. She just backed up a little and let loose. Now her whole back end is a gross mess. Any advice on the best way to go about cleaning her up? She has some chicks under there and I don't exactly feel like it is a sanitary place to be right now! I figured I could probably muddle my way through it, but if there is a way to get the unpleasant task done as quickly and painlessly as possible, I'd appreciate the advice.
