My two RIRs both have raw, red butts and missing feathers on their butt and top. The redness and raw started when one of our chickens turned out to be a rooster (this was a surprise)! Once he started getting at the ladies we got rid of him. That was at the end of January, so I expected the birds to be healed by now, but it isn't healing so I was wondering if there is another problem and what to do about it. I checked for lice and mites and didn't see any. I've also been watching for the other birds to be feather picking and didn't see any indication of that either. Anyone have any thoughts and suggestions? I've read a few other posts, but not really sure what to treat it with. Thanks for your help!
