Hey there, so one of my hens got frostbite during the winter, unfortunately. This was a few months ago now. She lost two of her toes to it. I was hoping she would heal in the spring but it's summer now and she still limps quite heavily. She is very strong and, despite being tiny, is arguably top chicken. Is there any way to treat her toes, which are still swollen and white? I just don't want her to be in pain. She seems completely fine besides the limping.
