I didn't know they did it either Emma.The first year we had him I thought he was ill and kept waking him up and putting him under his lamp but he just went back to sleep. My daughter has a friend with a beardie and he said they do it every year. His has just woke up too. I don't change anything in his set up, the lights still come on every day, he just doesn't come out from under his log. The only problem is, I don't know when he's going to wake up so my regular order of crickets backs up. I have had to feed them to my chickens, they don't seem to mind though. The chickens not the crickets.
It is lovely to see him again. We were all gathered round his tank saying hello. He just yawned and couldn't understand what all the fuss was about.
