I incubate at 75F, for no particular reason. I get about 50/50 ratio on sex,
including clutches that hatch one male and one female.
FWIW. The last thing I "heard" was that you would get females with widely varying
temps daily and males with constant temps. It was also important to do this early
on w/in the first couple of weeks of laying. Whether this is "kosher" I cannot say,
I have not tried it, this is pure hearsay, but should not hurt the eggs in any
event if you go this route.
