I have several T. Albos. I rehoused them feb.26th with a few others as they all were getting big and needed some deeper substrate and space. One of them, has always kept it's burrow covered up. All of the others except one of my t. Vagans which is the same way, have all now dug back out from the rehousing and molting and are back eating. These two always seem to stay down deep buried. The food disappears when they want it but sometimes it's still there. I wouldn't stress at all. Smaller juvies and slings like to feel safe inside Thier wholes. N they can go through something like a hibernation and some even do this great hunger strike thing that can drive keepers absolutely bonkers with worry. Just keep doing what your doing w offering pre-killed and water. I'm sure everything's going good.
