This is not true and here is why ....
His incubator is set on 27 - 29oC and produces a mix of Males and Females. I know this as he has held some back in the past seasons and have grown them up for breeding. If anything he has ended up with more females!! His incubator is also affected by the air temp outside of it, so does fluctuate. He runs an air-conditioner 24/7 in the room with the incubator, heating in winter and cooling in summer. This does help the incubator from getting to hot / cold, but does still have a 2 to 3 degree fluctuation. From information that I have read the temps that we incubate at shoud give a mix of sexes with the Red-ears and Reeve's. However I have not experimented as to what temp produces more females or males. More work is done worldwide with Red-ears as they are more abbundent and are very easy to incubate.
