The other night I noticed my yellow female digging what turned out to be a "practice" hole. The next night, she was digging again in a new spot, in the morning, when I checked,the hole was abandoned, and the remnants of eggs were laying around. She had chosen as her spot, the undiscovered nest of another. There was one undamaged, and fertile egg, which I have put in the incubator. The third night, she dug again, and left me three eggs. So, actually, I guess the single egg was a bonus rather than a loss.
