My hen is limping on her foot, but I don't see anything really wrong. I took her inside and soaked her legs in Epsom salts, but she isn't showing relief. I've felt her leg and she doesn't show pain when I exam her. She does hold her leg up so she doesn't put weight on it though. I found this area on the bottom of her foot, but it's not inflamed or swollen. Can someone tell me if this is bumblefoot? I don't want to dig into this if it's not. Thank you.
