For those interested in gecko breeding, sexing a pair of geckos is the first step. Males and females can be distinguished by the size of the pores surrounding the vent at the base of the tail. Female pores on the underside of the gecko will be nearly invisible or very small. It's also essential to have suitable housing and privacy for a breeding pair of geckos, as well as adequate food. Gecko breeding should not be attempted until the female is old enough, preferably at least 18 months of age, or she could be at risk for complications.
Inexperienced gecko breeders will need to do some research on the topic. Asking a local breeder or picking up a book at the pet store can help. After the potential breeder has been well educated on various aspects of gecko breeding, he should acquire a pair of geckos that are mature and healthy. The tail of a healthy gecko will not look bony or fragile. A plump tail and eyes that are free of discharge are good indications of a healthy animal.
Good diet is essential, especially for the female. A diet that is lacking in calcium could result in female gecko egg-binding, which could be fatal. It's important to increase calcium in the female's diet by adding a powdered supplement to her food.
Proper housing is a must for successful gecko breeding. Geckos will not breed in open spaces, and will require some type of shelter or privacy hutch or log. Pairing the male and female gecko for several days should initiate breeding. If minor bite marks are noticed around the female's neck, this should not be of concern, as the male will often grab the neck of the female while mating. If, however, there are visible signs of aggression towards the female, the two should be separated to avoid potential injury.
The female may lay a clutch of two or more eggs. An incubator will be necessary for maintaining warmth and proper temperature for the eggs. Incubators may be homemade, although store-bought varieties may be better for beginners. It may take up to two months for the gecko eggs to hatch, although higher temperatures may accelerate the process.
Hatchlings should not be housed with larger geckos. Large geckos may become aggressive towards the smaller hatchlings and injuries could occur. To ensure the safety for all hatchlings, shallow water bowls should be used, which will prevent the babies from accidentally drowning.
