Incubation and heat question

[bustnova]

Is it true that the temperature you incubate your eggs at is a factor in the sex? I am just curious. I heard some one ask how to get a larger amount of pullets, because he got only three pullets and 17 roosters from his last hatch.

This is interesting. I have heard it mention from several sources that the female embryo is more likely to die at higher temps than the male. That doesn't mean that lower temps will create more female,just that they may be able to survive better. This past year I incubated at the normal temps and got mostly males,way over the expected 50/50 split. The broody hens fared much the same, and it was a hot Summer. I am incubating now and I'm keeping my temps between 98.8 and 99.0,so I guess we'll have to wait and see.
