I got my beardie a few days ago and it was really calm and docile. Yesterday I could not feed it crickets because I was out and did not have time to go to the store. I looked at him today, and he was freaking out. He was running around the cage, scratching at the glass, didn't want to be picked up. I got crickets and gave them to him today, which he gobbled right up. He still does not want to be picked up, just runs away from my hand.
What's wrong?
