I would dig around, usually around the base of a plant or under something and they will go deep sometimes. I used to find eggs when moving plants around or changing soil even after doing regular sifting. When I sold all my fantasticus and decided to clean cages and dump plants out before moving I found 8 more eggs. All hatched out!see, ive only had one egg ever buried, and i was just lucky to find it. im wondering if i should be digging for my eggs right now...
