Quote:
Renee, incubation temps have absolutely nothing to do with determining the sex of a chick, it is a myth. The hen carries the sexing chromosomes. She alone determines if the egg will house a male or female. So nothing you are doing is wrong. And remember, you had a very high hatch rate last time. That is what is important with hatching.![]()
I have read that female embryos may be more susceptible to incubation temps being too high. I your female embryos quit, but not your males. You would end up with more males hatching. I don't know if this is true.
