An Odd Problem...

[Uffern]

I went into my herp room today and noticed one of my Juvinile dragons was on his back. I went to inspect, and he was still alive. I picked him up and his spine seemed to ahve caved in about 1/3 of the way up from his hips. His hind quarters are completely limp, and he doesn't seem to have and feeling in them. To me, this would suggest a broken spine. I can't, however, figure out how this would happen. If anyone has any ideas, or better yet, experience, please let me know.
