You'll have eggs after about 5-7 days which will need to incubate. You can see the eggs, they are about 1-2 inches down in the soil. You'll have to make sure you spray that soild to keep it damp. If it dries, the eggs will die.
Put the top (this will keep moisture in) on the breeder container and put it in a warm spot. Generally within 2 weeks it should be swarming with pinheads. Be sure to put another breeder container in with the breeding colony so you can keep it going.
It's easy, just remember, the colder it is, the slower the cycle is. You can speed it up by putting the breeding colony on top of a heating pad as well as the incubating breeding container.
