Leopard geckos are relatively easy to breed. If you decide to breed leopard geckos, do not house the male and female together because this can cause stress on the female gecko. Letting the male and female mate all the time can cause health concerns particularly on the female.
One male will mate with several females so people tend to keep them in groups of one male to 3 or 4 females. To detect a pregnant leopard gecko, the female gecko should have a noticeable bump on each side of her abdomen. Females will usually produce multiple clutches of eggs during breeding season. Pregnant females will most likely use a laying box if provided.
The eggs should be removed from the egg laying box and incubated in vermiculite with a 1:1 ratio of water to vermiculite by weight. When incubated at 85 degrees, the eggs should hatch in about two months.
The newborn geckos will not eat until after their first shed which usually takes about a week. It is best to house the hatchlings separately and feed them with appropriately sized insects.
