I'd try confidence exercises then. Spend as much time with your hands in the cage as you can. This will get him used to you poking around, and each him that hands are no threat. I'd also try leaving your hand flat in the cage, and allow him to crawl on it. Reward him for sitting in your hands. I tend to do this exercise right before feeding time so it's also associated with getting dinner. The more comfortable your ham becomes with your hands, without feeling restrained, the less nervous he should be. Good luck, if you have any other questions, please ask
