Can't tell if MBK is being weird, or not.

So I've only had this MBK hatchling as of a week since Friday, so I don't know what is "normal" behavior or not.

For the first several days he was relatively active--I'd catch him out and about, etc. Fed on Tuesday, was fine.

Wednesday, I didn't spot him at all (he's in another room, so I spot check). Ditto Thursday. Friday he peeked his nose out and I dug him out to handle him briefly, then put him back. Saturday and so far today...haven't even seen him stick his nose out. I also used to sometimes see him curled up in one of his hides--as of Wednesday, that is no longer the case. He seems to ONLY be hiding out in the substrate.

He has 4 hides--one warm, one cool, two hanging out in the middle. Temps are currently 85 on the warm side, 71 on the cool end. Humidity is about 50 right now. It did drop low the other day, but I fixed it.

Has he maybe just settled down and decided to hide in the substrate most of the time? I see signs of his moving about but never see him anymore. Could he be sick? Should I leave him alone or try to find him? Wait until feeding time and see if he resurfaces to eat?

I've thought about removing some of the substrate (it's pretty deep) and making it so I don't have to have a mining expedition if I want to find out where he is.
