What sort of hiding places do you have for him? Jack are normally fairly nervous, but with plenty of places to hide, he will feel more secure. Is he a new purchase? It also takes them a little time to become acclumated to their new surroundings. HTH

I'll try and find some sort of structure for him to hide in. I've had him for over 6 months now. Thanks for the info.

Cpincidently, I was going to suggest places to hide, like shale or clay pots.
