Anyone notice people selling thier 2 month old cresteds as "low temp incub. so higher odds of females", this is such a scam. And very unethical in my opinion. Its a shame cause most people probably dont even know.

I dont know about anyone else but I have yet to see any concrete evidence about temp dependant sex in cresteds. I have not seen anything of the sort in my experience and I incubate at an average of 75-76. I have tried quite a few clutches at 70-72 and still saw no real noticable difference.

Has anyone gotten results on this issue? I'd like to know.

Last spring I moved my breeding trio to a new and bigger tank. I ended up putting the old tank in the basement. I had left a few potted plants and all the substrate in it. Well, after about a month I went to clean the tank to make room for something else. To my surprise I found 2 hatchlings and after a further search found another 2 eggs at the bottom of a potted plant. Which ended up hatching about a week later. The temps in my basement range from 66 to 68 in the spring. All but one turned out to be female.

This could have been a coincidence. I have heard this theory before, but I don't have any concrete proof. I have had clutches with a higher ratio of females to males at normal incubation temps before as well.

P.S Tip Of The Day.

Always check the bottom of the potted plants!

Thats interesting cause I havent seen anything like that in mine.

I wonder if anyone that breeds in large numbers on here have seen anything that backs up temp determined sex ratios?

is that you end up selling most of them before they reach sexable age, thus it is hard to tell what the statistics really are for a large sample. If you look at Anthony's site he only keeps the really great looking ones and sells off everything else, which is pretty typical of what I imagine most larger scale breeders do. So the big boys with a statistically meaningful sampel, do not have any results. Personally I incubate at 75F, get more females than males, out of the ones I keep, but again, most are sold as soon as they start to throw color or reach a size where customers use all sortz of arcane methods to attemt to divine the sex.
