I have 19 chickens and only one has this problem. Her legs seem swollen and flaky looking and her feet look bumpy like witch's fingers. Maybe warty looking. It's hard to discribe but she roosts a lot and it takes her some time to jump off to eat. I'm think it might be painful for her. Any suggestions on what it might be and what I could do for her? I might have to take a picture and post it.
