My dragon is gravid and about 3 days ago she stopped eating and started becoming very restless. I put her in the lay box I made her which is sand and soil mixed together and she only tries to find a way out of it. I was wondering if I should try just sand, just dirt, or something else?
The mixture you have is fine. How deep is it ? It should be about 8-10: deep, and damp enough to hold form. Pile some up on one end and start a cave with your hand.
