does temperature of incubator determine sex of chicken?

[davimi]

I was going to incubate some eggs in the spring, but I really do not want a bunch of roosters. Is there any way to incubate the eggs so that I would get more hens?

 

[BJS]

No. Otherwise the large commercial facilities would hatch almost all hens instead of sorting them out afdter they hatch and destroying the male chicks...

No.

You can use that method to influence amphibians Want to hatch some alligators?

Been covered a dozen times. Nope. Too high of temps or other incubating problems can end up killing off more pullets than roos so some begin to think things like that impact gender but the gender of each egg is decided by the hen at the time the egg is created. Eggs have a gender before they are even fertilized and coated in a shell. Nothing you do is going to change that.

This subject was brought up by me like last week..i was thinking it did but then after reading much material on the subject found it only applied to reptiles. As chickens are kinda scaly you would think it would apply bun alas, no.

LOL....my son was just telling me this earlier. We had decided to crank up the bator and I let him choose about 38 eggs to put in and he said " now go get on the internet and see what temperature you need to produce hens." I had to explain to him that this was an impossibility.

I know this is an old thread but I came across the article that addressed this and figured there must be a post in this forum where I could share it for others to reference. It's pretty old and since I haven't heard anything regarding hatcheries using temp to sway their hatches, perhaps it's been disproved. Regardless, it's interesting. I've had a couple pullets that looked and behaved like cockerels...both had sizeable combs/wattles that reddened out before their cockerel hatchmates' did. One was a nasty bird that found great pleasure in biting/attacking. Regardless of their development, they were definitely hens that laid eggs. Wondering if there is any merit to this observation, if that's why they were so odd? https://www.independent.co.uk/news/a-drop-in-temperature-can-change-the-sex-of-chickens-1238516.html

Yes, an old thread and an old article. That article looks like it was published in 1997 and it was to try to get all males. The broiler industry has not been transformed in those 25 years so I'd guess it has been disproven. It goes against science anyway.

The article has basic misinformation in it anyway. The female broiler chicks are not automatically killed. They won't grow as big as the males but they are generally sold as Cornish Game Hens at a fairly young age or grown out for 6 to 8 weeks and sold as regular chickens, just a bit smaller than the males. Still, all males would be preferred.
