one of my hens has been limping some, i watched to see if she would get better but shes gotten worse. i caught her and looked at her foot and on the top of her foot her skin is missing. looks like the skin got sliced off. it was dry, so i scrubbed it with some betadine and water, then sprayed it with blue-kote. i have her penned by herself because i dont want her to range off too far and not be able to get back. she hops and gets around quickly and fine, but shes not wanting to bare weight on that foot at all. anything else i can do for her? im going to keep treating it like i did but im wondering if i can/should do more?
