How long have you had him? If he's new, he's probably getting used to things, but will likely show himself more and more with time. Feliz, my BCC, spends half his time in hides and half his time both and out (at the same time) or out of his hides. Behira, my BCI, is usually in a hide, but with half her body, or at least her neck, checking things out well out of the hide.
