I have heard that, and in the name of science tried it last year out of six I got two very warm doodles and two toasty hens...one quitter and a mutant with stubby legs and a huuuge head.

I read temperature can be a boy vs girl factor. Not that you can make them go one way or the other but girls can handle more heat so if it's a high temp hatch you'll end up with more girls. Only because the boys don't survive. Or maybe the temp was the other way.... now I don't remember.
pissed.
Cappy Mama!
