Extreme Temperatures

Ok, I've been doing some research on incubation temperatures and I need some advice from people that have experience with this.

We all know 80 degrees to 84 degrees gives us the highest percent for hatching females.
86 degrees to 90 degrees gives us the highest percent for hatching males. With 85 degrees having a 50/50 females to males ratio hatch.

My question is this, I read where a breeder was incubating males in the 92 degrees range and females at 94 degrees range. Have any of you done this, and if so, how did it go?

If females are born in hot conditions they are called 'hot females'. They are usually aggressive and will usually not breed.

It also depends when during incubation those temperatures were reached. If the earlier half of incubation was at those temperatures, then you have a chance of getting hormonally screwed up geckos like Shawn said. However, some breeders 'cook' their eggs by incubating them at high temperatures during the later half of incubation to reduce melanin production produce prettier, brighter babies and have faster hatch-out times.

I'd be cautious of the high temps not only for the "super" females as they are called but also the embryos don't have as long to develop, hence the short incubation period, and could hatch underdeveloped or even deformed. In my opinion the 3 weeks to set the sex then raising temps to get brighter, more beautiful geckos is a bad idea and should be avoided. I say let genetics be the determining factor for color and its intensity.
