OP I must agree with Craig on this one i found it just too odd something is up. This thread didn't leave my mind .... another thing to consider is how big is the hides you are using ? They like a tight fit, very tight if the hide is too big they will search the viv/container constantly and only rest in the hide for short periods of time. Sometimes they wont even use it for a quick rest.
Clutter the viv/container with fake plants as much as possible i have 3 hides in my big viv, but my ball is happy there is almost not space for a mouse as he grows i will take a few things out but replace them with smaller objects, they really are shy animals by nature, very shy. Its true each snake has their own personality etc, but not to this extent.
Like the rest said maybe invest in a second thermo gun to make sure i triple check my vivs 3 times a day not open and close but i check that stuff is in order.
There is no way for them to tell us they are unhappy unlike a dog or cat, best is to stick with what has been a proven all these years.
I know you might not like this but i think its best to get stuff on point and start from scratch and triple check everything and get the snake into a safer routine. The streets is not really a place for a snake.
