For the last couple of weeks I have a hen that keeps pecking at both of her feet until they are all bloody. She just sits on her roost all day and won't come down to eat or drink hardly at all. She seems fine other than there is something bothering her feet. When she stands she keeps shifting her weight to either foot and when standing can tell it is bothering her as she keeps going to her feet like there's something wrong and can't get back up to her roost fast enough. I'm not sure if the problem is she started picking at her feet for some innocent reason or other and now the scabs on her feet is what's bothering her or there was some other unforeseeable problem that made her start picking at her feet. I gave her a foot soak and put some polysporin on it, but I'd like to know if there is something else besides the sores from her pecking that I'm dealing with? The other chickens do not bother her at all and she is the one doing all the pecking at herself. Like I said I'd like to know if there was another problem that developed that made her start doing that or if it was the pecking that has caused the problem? Her scales on her feet and legs are normal and it doesn't look like she has mites or any other pest in her feet. Don't know...Please help as she seems to have started picking at them a lot worse today. Thanks.
