I had gotten my bearded dragon a pet expo recently and they were doing perfectly fine. The temperature is right and they have UV lighting. I feed them live and they usually attack the crickets immediately. I noticed for the past week or two that they have been spending all their time under their heating lamp, and seem uninterested in their food. They have also already shed and they appear to be lethargic as well. Their skin is a bit wrinkly on the sides as well and they have been getting stress marks. I really love my beardie, and would appreciate any help if possible.
