I wen't to the N.A.R.B.C. last september and an Ivory breeder had hatchlings that were "sexed". I was woundering if they had to get a blood sample or something? The only way I read about how to sex a Sulcata was waiting until they got older.
Sexing Sulcata Hatchlings

Incubation temperature determines sex, MOST of the time. The breeders thermometer might not be accurate, something could happen during the 3 months incubation period that changes the temp setting on the incubator, the temp might be toward one end or other of the scale, but far enough from either end to result in a mix of sexes, etc...
They may have been talking about temperature sexed, though that isn't always reliable. I'm pretty sure someone has posted on here that when they incubated for female, they got all male.
Too slow.

Well how did they know they had incubated all male? Did they keep track of them until they got to the size where they can tell? I know it's a random question lol but thanks guys I didn't know incubation temperature determined sex.
Either they kept them or kept in touch with the folks who currently had them. Not sulcata, but I know with my Stars for example, they were incubated to be females. The ones that are now old enough to be sexed are turning out to be all males. Buying any hatchling or even a young tortoise is a gamble. Sure there are ways to increase the odds of getting one sex over the other, but we are talking about nature here. Nature finds a way to make sure both sexes are in the world to keep the species going.

That may be me he was talking about.
But it was Manouria. They are a bit different from most tortoises. I have recently learned that I should be keeping my manouria eggs at 84F degrees, and I had my incubator set for 86F. The trouble with this new knowledge is that it doesn't tell me what temp is female and what temp is male. So I'm thinking that in the Manouria species, the higher temp is male. Just the opposite of most other tortoises.
The reason I know about all of them being male is because I kept 6 of the offspring and all 6 are male.

I may have been referring to Yvonne, I was going off memory alone but went searching for it and found this:
