First time snake owner

[MoshPotato]

Hi, I guess. Im Sean, and I'm finally the proud owner of a snake, it's something I've been looking forward to for a long time. I purchased a 2 month old Florida King snake from a local reptile store/breeder, and though I spent a couple of weeks doing my homework on colubrids (king snakes especially) I still had a couple of questions, mainly regarding behavior.
Nagini (that's what i've opted to name it) had a very stressful ride home as I live a couple of hours from the store. I allowed him some time to adjust, then carefully introduced him to his new home, a 10 gallon tank. While it does have a hide, he opted straight for borrowing in the substrate and as far as I know he hasn't come out since. Is that normal behavior? I'm used to my lizards, who typically spent days exploring their new home. I'm assuming it's because he's just nervous, being as young as he is, because he musked on me multiple times transferring him to his new home. So, is this typical behavior that I should come to expect, or will he grow out of it?
Thanks for the help, I'm a total noob at this and want to be prepared as possible.
