BLUE TONGUE SKINKS

Hey yall! Ive noticed this slightly odd behavior from my northern the past couple of days where she leaves her mouth slightly open while she basks and sleep. Its been warmer lately and the room she resides in has been getting pretty warm during the day, so I believe she might be just thermoregulating. Shes been incredible moody lately, but I believe its just because shes starting to come out of brumation. Other than than, shes eating and shedding normal with no crusties, excess mucus, clicking/wheezing, or other signs of uri. Thoughts?

I've got one that does that all the time. He's one of my proven breeders and is 9 years old, never had health issues. And sometimes he's sticking his tongue out too. Just too cute. Nothing to worry about if everything is normal.
