Temps over 80 degrees cause a litany of things to occur:

Spinal kinks

Deformities

Death in egg before pip to hatch


Temps in the 74-78 degree range usually do not have these problems associated with them. Keep in mind, that though the temp may be a CONSISTANT 74-76 degrees, all it takes is one good temp spike for a prolonged period of time(10-24 hrs) to cause the above anomalies to occur. I would err on the side of caution and keep the temps low, factoring in such things as climatic weather conditiond(i.e. Santa Ana Winds) which can and will change things, but not for the better.

Additionally, I have found that higher incubation temps DO affect sex ratios, but again, they also usher in a litany of problems even more serious(As stated above)



Sincerely,
