I bought my bearded dragon yesterday, and he has some neurological problems, so he cant walk very well or catch crickets very well. He has managed to catch about 8 or 10 with my help, but refuses to take them from my hand and whenever I try to move one near him, or move him so he can catch them more easily, I think he gets spooked and refuses to eat anymore after that. He has already pooped so I know all his insides are working, but I'm still worried. Anyone have anything I can do to help him? Substrate recommendations so he can move more easily? Etc?
