Hi,

I have had 12 Borneo cat gecko hatchlings since the beginning of the year and I am noticing all of them are males (thankfully they are easy to sex out of the egg). I am incubating them in a room that fluctuates in temp from 68-80 right now. I have always gotten a fairly even sex ration with my other locality cat geckos, however I find it odd that out of 12 babies, everyone would be male, without something causing it.

I would be interested in hearing how others are incubating there eggs and what there results are in terms of the sex ratio. I need to start incubating for females!!

Thanks Derek

Interesting.. I have incubate them under 24-25C and have 70-75% females....

Marcus and I have in the past discussed TSD in other locales and never found enough evidence to prove it. However, in the Borneos, it could be different. What about your friend Steven? He's hatched a lot of Borneo eggs out. Have you asked him what his ratio/temps have been? With the other locales, I've pretty much always (except for some experimentation here and there) just left the eggs to hatch at whatever the room temp happens to be and have always had a pretty even ratio.

I've got 6 cooking at 78-83. Probably a bit warmer than most but we'll see what happens!
