So my new BP, I've had about 2 weeks, still havent handled, but unfortunately, he still hasn't eaten. Once he bit and constricted and then just left the mouse in the hide.
I've noticed that he sometimes sits with his head and neck pointed up to the ceiling. He'll do this for maybe 3 minutes, usually less. More often, he'll lie with his neck pointing out the hide, and his head resting on the waterbowl, at an angle, still pointing up. I haven't noticed any other IBD type symptoms. Is this a RI, or is this just normal behaviour. Obviously I'm pretty paranoid because he's my first BP and STILL hasn't eaten.

Temps are good- 92 hot, 83 median, 78 cold
humidity was pretty high for the first week, but has since gone down to 60 for the last few days
hide is quite big, but he wouldn't go into the smaller hide
he looks healthy, but to be fair I've never owned a BP so I just mean he's moving well, and doesn't look TOO skinny, (he's defo lost a bit of weight though since he hasn't eaten)

please help, really don't have money for a vet but obviously if it's super necessary I'll beg borrow and steal if i have to
