Brady,
Your experience sounds similar to one we recently had, where our chicken's leg got caught up in some chicken wire and she was found dangling upside down. We were not sure if it was a break or torn tendons and could not find a vet willing to look at her. Her leg also dragged behind her.
We seperated her from the other chickens by putting her in an old dog cage, gave her access to food and water, placed a heat lamp over her cage and gave her reiki (rake-ee) treatments. I wasn't sure that she was going to ever walk again as that legs just dragged behind her the whole time. But a few days later, we found her standing and walking. She has a limp, but gets around fine. As one who believes in the healing power of reiki, I like to think that had much to do with it. But one can't rule out time. Beacuse of this experience (and others in the past) I started a thread on this board about reiki for injured chickens. If nothing else, you may want to consider it as an option. Good luck and hope to hear that your chick is walking soon.
