I posted yesterday that my 13 week old barred rock had a really large crop that was sticking out. Today it is an open wound, the feathers are all matted around it, and she is bleeding. I just got home from work to see this. I'm not sure what to do. I have peroxide and first aid cream. I also have some tetracycline hydrochloride antibiotic in powder form. I'm going to get her & try to clean her up...but I'm not sure what to do next. Or what the heck it is! Any help would be appreciated.
