Bearded dragons can be pretty derpy sometimes, but sometimes the derp factor has an underlying cause. Just to make sure, we're going to need some more information:
- Can you post a picture of him?
- Temperatures? (basking, ambient, and cool)
- What type of UVB are you using, and how old is the bulb?
- What type of substrate are you using?
- What are you feeding him, and what is his feeding schedule like?
