Hey folks!! This is my first attempt at hatching some cicken eggs.

YEs and no.

WHen an egg is layed the gender is already determined by the hen. (in mammalian genetic, males carry XY sex chromosomes; in chickens the hens cary the ZW sex chromosomes.)

Increaseing the incubating temperatures above the normal 99.5 will start to kill off the males, the higher the temp the more males die off. THerefore the females will still hatch but the overall hatch rate will be down. ( High temps will also kill female eggs; too high is102 ish).

Does this make sense??

Yes, Thank you.In fish, water temp can determine sex. Thats why I asked.
