My 50 yr old CDT dug a huge hole and hung out in it for about 3 weeks. After that she has had nothing to do with it. She has returned to our garage to nap during the day and sleep at night. The hole goes under our house. I cannot get down far enough to see if there are/were eggs. The deal is.....she is an only child. She has not been around another tortoise to mate. I am wondering if she can lay eggs but they are not fertile. See photo of her in hole. I moved the cement umbrella holder to prevent it from caving in on her. Thank you.
