welcome to the forum. hope you enjoy it and gain all the knowledge you need and more. know iv learnt loads and always finding more all the time. This is by far the best forum iv found, believe me I'm on loads, but this is the best.
as for ur snake hiding, it's a perfectly normal behavior of some snakes more than others. We have some corns that never seem to move out of their hides, others never go in their hides. just depends on the snake. Some of ours have no hides at all as over the years have never been found in them. Besides, unless u watching it 24-7 u will never know what they doing all the time. we have some that revelry active all day, some all night, some just first thing in the morning and some just at dusk. it really depends on the snake in question. I wouldn't worry unless u know of a stressful situation which may of triggered new behavior (obviously just prevent it happening again) or its not feeding. Even then, it could be that temps are slightly lower, sometimes it's hard for humans to notice a small drop in temps, an animal which is temperature dependant will feel a subtle change more than us. as I said, I'd only worry if it wasn't feeding. hiding is perfectlynormal
