well first off the eggs are fertilized INSIDE the female, you dont wait until the eggs are laid to be fertilized. And also, please research before you breed, usually you dont make any profit on breeding them. You need to ready for up to 30 hatchlings and must have housing for everyone, 5 hatchlings per container. And even then, the female will lay more clutches, leading to at least 60+ hatchlings that you need to have housing for, correct lighting for, and supplements for, let ALONE food. These guys will eat thousands of crickets a week, plus you need the greens. Besides just the caring for, youll need to find homes for everyone, and that is often hard to do. You will often become desperate and sell for very little, losing money on the venture. And as yo7u are looking for homes for the little guys, they will be getting bigger, needing more room and fewer hatchlings per housing unit. It can be a very expensive venture. Do Research before jumping into this. Make sure you have the finances.
That aside,here is what i do. After they go out of brumation, i put them on the floor and see if the female is ready. If she is, i leave them alone, but watch just in case the male gets aggressive. And i wait. If i notice them breeding, i wait until its done and i put them both in their seperate cages. Within 2 weeks she will get restless and will need an egglaying box with 1/2potting soil and 1/2 sand, moist enough so it wont cave in. You will then need an incubator to keep them in at about 80-85 degrees F. During the gravid time (when she is carrying the eggs) give her as much as she will eat and keep her hydrated and make sure she gets LOTS of calcium. After she lays make sure she eats and gets hydrated and gets a lot of calcium in her, and do this every few hours after laying until you feel comfortable.
