Why haven`t anyone entered the sex ratio and more info of the juveniles? Frisei can be brumated from 24-30*C or even less and more. BUT what is the status of the siblings? Do they eat(They should do ANY time)? What is their size? What sex? Are they without any skeleton problems?
Questions that should be asked............. or not?
Personally I have good results with 26.3*C during incubation. That gives large healthy animals and a nice sex ratio (for me)
Best wishes
