Is this behavior normal?

Behavior sounds normal to me as well. And I agree with Aaron that the snake is likely showing signs he's hungry.

I've gotten to the point with my BPs that l let them "tell me" when they're ready to eat. They're adults though, so a little different.
My point is, the behavior you're describing is indicative of the snake "going into feed mode".

I think an appropriately sized meal is all he needs
