Well I caught him and took a close look at the injured leg. It was mangled just below his knee so after a lot of reading I chose to amputate the leg just above the injury. I made sure it was healthy tissue that was still attached to the bone. I now have him in a small critter cage that I keep on hand. I put in plenty of leaves to make him hopefully feel like he is hidden and safe. Guess I'll keep him in house till the leg heals and he proves he can escape predators and catch food on his own. Rather than catching bugs to feed him couldn't I go to pet store and purchase small crickets for him to eat or do I need to catch him local bugs? And I'm sure I will need to keep his cage high in humidity by spraying spring water on the leaves.
