My BCI "burrows"?

[c0r3yr0s3]

Hello! So, I purchased Rojo, my (roughly) 6-month-old BCI a little over 1 month ago. I've got her on Eco-Earth right now, and I rarely see her because she's usually burrowed (I'm not sure if that'd be the word) down in the substrate! She's a healthy little girl and her husbandry is correct. Is this completely normal or should I do something? I'm just worried about her digging down to her UTH. I check her every time I hold her for burns, but she usually does it in her cool hide or on the cool side of her tank. Thank you!


Husbandry
Ambient- 78°F
Cool- 76°F
Warm- 79°F
On UTH- 91°F

- I JUST HAD HER OUT FOR MAYBE 10 MINUTES AND FORGOT TO PUT HER LID BACK ON. SO YES, IT'S COOLER THAN IT SHOULD BE. I GET MORE ACCURATE READINGS IN A BIT. IT'S USUALLY AT 80-89°F!

Humidity- 54% - JUST MISTED!

Mine does the same thing. He's healthy and very active when I take him out to play. Every once in a while, he soaks in his water dish but he spends most of his time buried. It's kinda funny when I show him to people because I have 3 bp's and a corn so they are never suspecting a 6' boa when I dig him out and everyone so far has taken a step back and just said "whoa!"
