We have a barred rock who has a large chunk of poo build up on her rear end. Her poop is healthy looking, it is just dried and matted in her feathers. We live in Minnesota and with the cold weather at first I thought it was just freezing on but I kept her in a warmer place for it to "thaw" out so I could clean her up. That helped a little, but it seems that it is just very hard and I can't get her clean. I don't want to soak her because of the time of year and am also afraid to trim her for the same reason. I should also mention that this girl is the one that likes to poop where she lays her eggs and loves her cubby so much so that is how I think she is getting this build up. Any suggestions?
