Crested Geckos lay eggs 4 to 6 times a year. Females generally lay two eggs at a time (never more than two) and in some cases one egg. These are deposited in moist (soil) substrate.
The incubation period depends on the temperature, at lower temperatures it takes longer for the eggs to hatch, while at a higher temperature the eggs will hatch faster. At a temperature between 26 and 29 degrees Celsius it takes about 65 to 80 days for the eggs to hatch.
