Is it normal?

My BP stays in his hide most of the time. He ate thursday but since then he stayed in hide most of the time.

Yes, that sounds normal. That's what BPs do: hide

A hiding BP is a happy BP.

BP's aren't display snakes. They tend to hide all day and come out for a few hours at night. (if at all)

Nothing to be worried about, this is typical BP behavior, in fact is is a bad sign if your BP is overly active.

But it's boring...HAHA...I wanna watch him do stuff

Then you got the wrong type of snake lol.
