I've had 7 chickens since they were three days old (June 15, 2012). One of my WPRs had what I was treating as "pasty butt" from day one, although as the weeks went on and I tried every cure I could find on this forum or Google and the dirty bottom continued daily, I began to think that perhaps the problem was something else. Now she is 7 months old and STILL, every time she poops it sticks, to some degree or another, to her backside. Over the course of a week, she goes from clean (just bathed by me) to a horrific, mess, loaded down with layers of fecal mater. She's been to the vet and put on antibiotics, she's been treated with apple cider vinegar and colloidial silver. I've trimmed her feathers around her vent until she's almost bald and, at times coated the area around her vent with petroleum jelly or olive oil. I believe that there is something wrong with the structure of her backside, because her tail droops down instead of curving up, like my other WRP and she walks with a funny waddle, even when she is clean. I bathe her about every week to 10 days and she is a horrible mess by that time. I'm especially concerned when we have cold spells, because the poo becomes this huge, frozen mass and the skin around her vent is red and sore looking when I bathe her. She seems good otherwise, eating, drinking, taking dirt baths and laying 4-5 eggs a week. So, does anyone have any experience with this sort of thing? Is there anything I haven't considered or tried? If not, can anyone give me the resolve I need to butcher her. It is my belief that this chicken would have been "culled" long ago if she were being raised by either a commercial farm or anyone trying to improve the breed, but she's been like a pet.
