Does humidity effect the gender of a chick?

[OneCrazyCowgirl]

I heard that humidity could effect chicks gender. Is that true? Does anyone know where I could find articles on this?

I think it was an article talking about temperature. It is not true, temperature cannot change a chick's gender though it is said that males can survive more extreme temperatures. Here's a link: https://www.backyardchickens.com/t/237217/about-incubation-temperature-and-chick-gender-anyone

Unlike some reptiles, a chickens gender is determined at fertilization. Sex determination in this species is not temperature-dependent nor humidity-dependent. The sex of a chick is determined when the mother hen add her genes in the fertilization process. If she contributes a W chromosome, the chick will be female. If she adds a Z chromosome, it will be a male. Males are homogametic (ZZ), while females are heterogametic (ZW).
