It's normal. I have OCD and Ave blown up ppl's inboxes with questions. All to find my snakes are happy and healthy.
I'd guess the missed meal was due to impending shed. My adult gets cranky and hides for her entire shed process.
When not in shed, a hiding snake is a happy snake.
Do you have an identical hide on both sides of the tank? (I couldn't tell,) and if not, that's the only suggestion I'd make.
(Also, wait for 3-4 feeds before handling, just one very them plenty of time to adjust.) I got a hatchling BEL on the 14th and till haven't held her. I want to, but want her settled first.
