One of my 2 Columbian Wyandotte hens has developed thick scaly looking stuff on both her feet. She gets up on the roosting bars and in the nest with no problem. She walks around the coop but refuses to go outside. I'm not sure when this developed as she is not a friendly girl and is standoffish. I caught her napping and was able to check her over, discovering her foot problem. I got her along with 5 other hens almost 2 years ago and to my best recollection she is about 3 1/2 - 4 years old. This group originally belonged to a neighbor who gave them to me. I didn't have a holding coop at the time and gave to my son's friend's family who had them for 6-8 months. I found out they weren't housing them properly and offered to take (had a holding coop built) them all. They agreed. All 6 were in rough shape, skinny and pale due to conditions kept in including lack of light (kept only inside a building with no light of any kind) and food. None of other hens from her group have this nor do my other 53 hens and roosters. She still lays eggs as well. I did my best at taking photos by myself so hopefully someone can have an idea of what she has. I don't know if its gout or something worse. None of the vets within a reasonable distance treat livestock, only one who did retired 10 years ago. Here's a couple photos of her feet. Any incite will be appreciated. Thanks in advance.
