Some (most) breeders can have both males and females larger enough, by weight, to potentially be breeding at 8 months of age, possibly even 6 months for males. I do not recommend it. In the wild these guys would mostly like not being large enough to reproduce until about a year of age or older. I've been keeping leos since '96 and breeding them off and on since '97. My first season breeding them I was young and impatient, breeding my male (who I still have) at 7 months of age. From 5 females that season I got a combined 90 eggs, with 89 hatched and 1 stillborn - all geckos first time breeders. Again, this is not recommended. Reproduction, even in captivity, puts a lot of stress on both males and females and especially so nutritionally. I've had males over the years completely go into full breeding mode and refuse food for months and lose a ton of weight.
My lesson learned from that 1997 first year of breeding leos was that 1) where's a freshman in high school going to sell or even keep that many baby leopard geckos and 2) I always give 2 seasons before breeding leos. 2 seasons equal as follows: initial season = hatching, season 1 = 1 year of age, season 2 = 2nd spring or approximately 18 months of age.
The moral and ethical questions you have to ask yourself:
- Why do I feel the need to breed my leopard geckos when the market is already beyond saturated?
- If I choose to breed my leos, where or how will I sell them?
- Am I prepared to properly house all the potential babies until they are at least 1 month of age and well established?
- Am I prepared to properly house all the potential babies should I NOT be able to sell, give away, or adopt them out?
- Will I be able to afford (= properly house) to feed all the babies?
- Will I be able to properly feed my female(s) breeder so that she maintains a healthy weight and proper nutrition?
- And a VERY real and sensitive question....Am I prepared to have to potentially cull any babies due to life-threatening deformities?
