I got some chickens a couple days ago and I noticed one of them limping a bit. I caught her and found a string wrapped around her ankle. It had obviously been there for a while. Is she going to loose her foot? I got the string out and cleaned it really well and added antibiotic ointment. Anything else I can do? Or is it too late? Here is the string that was wrapped on her ankle. Here is what her ankle looks like after the string was removed.
