I was wondering how successful breeders are with temperature sexing this species? Anybody care to share their experiences or insights?
In my experience (45+ years), TSD is relatively unreliable in Radiated Tortoises.I was wondering how successful breeders are with temperature sexing this species? Anybody care to share their experiences or insights?

I would say that TSD is about 60% reliable in Radiateds. However, it is 99% to 100% reliable in both Burmese and Sri Lankan Stars. I am not sure where your info on the Stars was gleaned, but those people who are not having the rate of success with TSD which I noted are most probably doing something wrong. I hatched close to 500 Stars (Burmese and Sri Lankans combined) and I am not aware of more than 5 or 6 (if even that many) which did not turn out to be the expected sexes.Do you have a guess as to how reliable? I am more familiar with Burmese star tortoises. With them it seems that when incubated for male they generally end up male. But, when incubated for female they get maybe 50% female, or worse. (Although, that wasn’t my experience.)
