I have never believed that temperature effected sex ratio except in some lizards, crocodilians and possibly turtles?

I don't doubt it's possible, but I have not seen any evidence of it in my personal collections.

Please keep in mind that too high is much more dangerours than a little cool in indigo incubation.

Temps. over 80F have been commonly attributed to causing spinal kinks and even worse deformities or death in developing indigo eggs. Temps of 76-79F seem to be ideal, at least in captive clutches.

If my clutches get to 74, I don't panic at all, but if I see 81, I start to worry !!
