Ok I bred Leopard Geckos before I got into Beardies and they are pretty similiar when it comes to incubation. So I was curious about something and didn't know if it applied to beardies or not so I thought I would throw it out there for all you beardie guru's. When you incubate the gecko eggs at a higher temperature at a certain time it will actually affect the color of that gecko. The gecko will come out with much brighter color than it would normally. Now genetically it can't pass on this brighter trait to its offspring. I am not sure why or how but that's what I have been told by some expert breeders. So, I am wandering if incubation temps would also affect beardies that way. Just something I was curious about so I thought I would ask the world's experts on beardie breeding ! lol
As far as I know spikes in temps or dips in temps at certain times of incubation can affect the sex. I dont play with my temps so I dont have 1st hand exp with it.
There have been quite a few people that have tried affecting the outcomes of sex color and size with incubation temps and it has been found that as far as beardies are concerned you can not temp sex them. the only change you get with higher and lower temps is length of incubation and how soon they eat upon hatching.
There's been a study of TSD (temperature sex determination) errrr something like that I used to have the link, and I don't think there was enough success to warrant further study. If I remember the results correctly the only increase in females observed, were actually infertile, or technically males that showed as females.
I am sure someone probably has the link, I know I used to have it archived but I can't seem to find it.
