Yep perfectly normal for a new snake to explore a little bit. As long as your tempratures and humidity are good your new BP should settle into a hide and start settling in within a few days. Let him stay in there undisturbed for a week and then try feeding, but the most important part like everyone else has said is leaving him alone. Like Snow Balls said, I think most new keepers who have problems with feeding have them because they tried handling too early, or were constantly making changes to the enclosure after they added the new snake.
