I have noticed that my new girl hangs in her cool hide WAY more often than her warmed one. Is this typical? (Sorry probably a pretty newb question)

If I pick her up from the cool side she feels pretty cool to the touch.

I am planning on re-doing her setup anyways, I want to give her a bigger one with more things like plants and such in there to climb on and hide in, and be a little more natural for her.
Right now she is in an oversized plastic tub with holes drilled in it, cool hide, hide on a heating pad and water dish and thats it. Its what I got her with but I want something a little more natural and whatnot
