One of my hens has lost feathers around her vent and the area is fairly pink. Its not bloody raw just redish raw(sorry for the description, but thats the way it looks). I have not noticed any of the other hens picking at her and she still looks and acts healthy. I just want to head off a serious problem if one arises. I did put some Rooster Booster on it tonight for lack of any other ideas.
It does sound like you have a feather picker, have you also checked for lice or mites? Do you leave a light on 24/7? That can aggravate the problem. It would be a good idea to try to find out who or what is going on to head off anything more serious. Do you have bluekote it's covers the skin and makes it purple might help. Bluekote also makes everything it comes in contact purple so beware when you spray it.
post a picture. There is another post about a rooster having hemmoroids and it didnt have a happy ending. Died of parasites and his butt was raw too. look it up and see if it is similar. good luck.
