After I researched when I suspected Tampico was going into brumation, I found out that most dragons do go into brumation. It's just coded in their DNA. When the temperatures drop, and they can tell a difference in ambient temperature even though they're in their tank with hotter temps, they tend to slow down and will sleep for multiple days at a time. So far Tampico is going through her brumation and when she was sleeping for 5 days straight, I turned all her lights off since she didn't need them (they conserve their energy and the lights aren't necessary at this time). She woke up a couple of times to get some movement, but never really ate. At that time I did turn her lights on so she could soak up some sun and UV rays, but she's gone back into sleeping and the lights have remained off. As far as taking him out while he's asleep and brumating, I do not suggest it because it may disrupt his sleep and make him brumate more so. However, if you are going to take him out, I suggest it only be to try and
hydrate him by
bathing and even then, you'll have to hold his head up for them if he's in a drowsy sleepy mode or if you're going to weigh him to make sure his weight is being maintained. He should only lose a few grams when he goes through brumation, like I said earlier, they conserve all their energy. This is just my opinion and what I've been learning through Tampico's first brumation. I'm sure others will chime in with different opinions and you'll do what's best for you and your beardie
Hope this helps!!!
