That's what happened this morning. She dug the hole, and filled it back in, but when I went to dig up the eggs I didn't find any. I was thinking she might have been spooked, or had something wrong. It has only been 3 weeks since she laid her first clutch so I think it's still a little early for her next batch.
My female sulcata doesn't fill them in. She digs 5 or 6 every year. She waits until the afternoon to start her real hole every year in January. I always have to rig some sort of heat for her, so she can finish laying and covering the eggs.
