No, he's probably in a shed. Just make sure you bump up the humidity in the enclosure to 70-80% and leave him be for a few days. When BP's are in their hide that means they're happy.

Shedding process can be identified by a slightly pink belly to start, dulled colors of the body, cloudy eyes (in blue) then a few day (2-5) days of looking kind of cleared up eyes then they'll shed. Just let him do his thing and make sure you keep humidity up.
