I have a female veiled and shes about a year and a half old. A couple months ago in October she laid her 2nd clutch of eggs. None were fertile. In the days after she laid the eggs, she would still dig holes in the bottom corner of her enclosure day after day. Then it turned into every couple weeks. Then she stopped. Sometime during mid-November i saw an egg in one of the corners where she had dug. I took it out and threw it away because it was a bad egg. Just today i woke up and found a big one in one of the corners and two other smaller ones spread around the cage. Why is she doing this?
