Does temp affect sex

[Pecknscratch]

I've think I remember hearing many moons ago that the temp of the egg determines the sex of the chick. My hubby also says this.
Have any of you heard of or had any expeerience with this.

I would think if it were true the hatcheries would be much better be able get just pullets.

I think that only applies to reptile eggs.

Good question, I've wondered that myself. Sorry don't have an answer, I would think it does or almost have to in a way on some very small level, but I also think you're right, if it were possible then the hatchers would've already mastered the art of hatching only female by now.

no, I understand the gender is determined by the hen in chickens...

Exactly! You'd better believe if there were a way to get more pullets than cockerels, they'd be all over it.

ETA: and I was expecting something very different by your thread title...

I was thinking about this very topic today, did a search and found an article that made reference to this issue. It (the article) said that, although temperature couldn't change the sex of the chick in the egg, he (the writer) knew of a veteran poultryman that thinks temperature could determine which embryos would survive. A lower temperature and more females would survive. A higher temperature and more males would survive. The change would only be of half a degree higher or lower.

For some reason I don't think the poultry hatcheries would really jump on that. Imagine how much more business they get when people order straight run but only really want pullets. You want 10 pullets and you get 5, of course you have to order more to make up for the 5 you didn't get. Not to mention they sold you all those roos. Not saying the temp affects it, just my two cents on how I doubt the poultry hatcheries would jump on it.

I personally would have liked to know the base or starting temperature that the poultryman was working from. The Fahrenheit temperature scale is a big one.
