can you really predict the sex of a cresty by the temperature that its egg was incubated at?
Ive read mostly views that say no, but a couple say you can.
Anyone out there who has bred them? Can you tell us about youre experiences?

In my experience I would say no you can't. I have tried lots of different incubation temperatures and methods and found that I still end up with a male to female ratio of 3:1. To date the temperature to sex link has not been proven even by the professional herpetologists i.e. Phillipe de Vosjoli and Frank Fast. It is an ongoing debate. In the new rhac book they seem to be getting closer to proving a link, in that they argue that it may be the fluctuations in temperature that is the key rather than set temperatures. I'm in contact with a lady from America and she produces 99% females. She incubates the eggs at room temperature. However, she lives in a hot and dry area and thus the day to night temperatures fluctuate greatly. I've tried incubating at room temperature but because of our climate the eggs just go mouldy.  |

I didn't think you could temp-sex cresties but you never know. I'm sure in a few years there will be some people who discover the secret like the American Lady. They will keep it a secret and make loads of money selling females.
