ok...hoping I can get some advice - tried the first time this happened a few weeks ago, but no one replied...PLEASE can someone give me an idea of what's going on and what to do. I have 3 Speckled Sussex with LOTS of thick fluffy BUTT feathers. I noticed one a few weeks ago with lots pulled out and white stuff and poop hanging out of her butt area. We caught her and cleaned with warm water (hard - it was dried and stuck), but got most and TSC said to spray with BLUKOTE which we did. She got better. Today I notice One of the others with some feathers hanging off and we thought we'd better check it out. Caught her and pulled up the tail feathers and lots of dried up stuck on poop again. So hard could only get some off, sprayed the Bluekote. The other looked ok, but caught her too and she had a large poop dried and stuck, could barely get any off, so sprayed and let go. The original hen seems to be ok. We have had these girls for over 3 years and no problems - why is this suddenly happening? How do we get this off and keep it off? HELP...
