I'm hoping someone can offer help as I am really stressing over one of my two Cuckoo Marans, which I got last September(2010) - I posted about this last year but got not response. If this is in the wrong category, please let me know - but it is an emergency in my mind! This hen was one of a pair who developed diarrhea that lasted longer than I had hoped. After following advice from the kind chickenlovers @BYC, that was resolved but her fluff feathers were a mess. She is extremely difficult to catch, but I did clean the poop off as best as I could. After about another month, it looked like the fluff feathers were coming loose, hanging down more every day. So I gently pulled to see what was happening and the WHOLE GLOB of her fluff feathers came out. She has been w/out butt feathers since December of last year; her skin is really red, looks like it would hurt like hell but doesn't seem to be bothering her. She continues to lay eggs, eats normally, ect., just has a very naked butt. The others are now beginning to attack her; she has chosen to isolated herself in a smaller run than the one the rest lounge in all day. They won't let her roost w/them at night. I am so sad for her, especially that her 'sister' Maran (they were inseparable) has deserted her for the Dark Side. She lives in fear/anxiety. I put the head bully in a separate pen, but think the others have learned her behavior; she joined them for a bit today, but they eventually turned on her and she went back to the other run. Please tell me what to do!!!!!!!
