Last night I noticed our beardie was laying on the ground on her cold side of the tank not moving. I picked her up and she was cold and stiff but breathing with her mouth open. I put her on the warm side of her tank on the ground. (there is a heating pad on the underside of the glass there). When I got up this morning I checked on her and she was still stiff and cold and her mouth was full of her bedding. I irrigated it out of her mouth and she seemed a bit more responsive. I put her on her climbing limb and when I checked on her a few minutes later she was hanging on by her front legs. I picked her up and she wasn't as stiff as before so I put her back on her limb (the wider part) and moved her basking lamp over her. Any ideas as to what could be wrong with her or anything that I can do for her?
