Oooh, poor girl! I have a 16-hand thoroughbred mare, and have worried about possible chicken injuries, as well.
I'd splint her feet with something to straighten them out, and try to keep her from moving around too much over the next day or so. I'm also a fan of apple cider vinegar and electrolytes. As long as she keeps eating and drinking well, she should heal up okay. At least she seems like a trooper and is managing the pain fairly well. If there are no open cuts, at least she shouldn't be in too much danger of infection setting in. I hope she gets better soon!
