I have this young (under 3 years) box turtle who doesn't favor his hind legs, he only uses them when food is out of his reach and then it's only after he has tried and tried with only his front legs. I put him in his pond and he only uses his front legs to get out, which takes a long time, He eats well, eats phoenix worms, red wigglers, super worms and nibbles at tomato. I have tried soaking him to no avail. He uses his hind legs more if I hold him. He is also starting to get an overgrown beak. I dust the superworms and red wigglers with calcium carbonate powder. He lives with another boxie of the same age who is doing very well and has gotten noticeably bigger (they were the same size). They both live in a 6 by 6 outdoor pin.
