Hey Guy, I would have to say after seeing so many things with these guys over the years that when they stay under a rock and do not bask for any length of time then something is not quite right. I have some that may stay more private when going through a shed but right after they do return to basking.

How HOT is her basking spot? If it is not TOO hot then theres some reason why she is not acting wanting to bask or chasing her food unless it's infront of her face.

* Is she dehydrated ? Look above her eyes and see if you see any areas that look dented in on her head above eyes.

* Have you checked her eyes? No infections or cloudyness? Parasites?
* Hows her poop smell ? Super stinky have it checked. All I can say is OBSERVE everything and see if you can come up with anything. Hope she perks up :0)
