What temperature to hatch more hens than roosters?

You can't control the sex of chicks by changing the incubation temperature. The sex of a chick is determined by its genetics, not the temperature it's incubated at.

Here's why:

* Chromosomes determine sex: Female chickens have two Z chromosomes (ZZ), while males have one Z and one W chromosome (ZW).

* Inherited from parents: The female chick receives a Z chromosome from both the mother and the father, while the male chick receives a Z chromosome from the mother and a W chromosome from the father.

Therefore, the incubation temperature only affects the development of the chick, not its sex.

However, some older, unreliable theories suggest that incubating at a slightly higher temperature might increase the chance of hatching more females. This is NOT scientifically proven and should be disregarded.

If you're looking for more hens than roosters, consider these options:

* Purchasing chicks from a hatchery: Many hatcheries specialize in raising chicks with a higher female ratio.

* Choosing a specific breed: Some breeds are known for having a higher female-to-male ratio than others.

Remember: Incubating at the correct temperature is crucial for healthy chick development, but it won't influence the sex of your chicks.
