Determining sex as chicks

[Paymoo]

So I’ve seen a couple times people say when the wing length on one chick is much shorter than the other it might determine roo vs hen…

Does this help determine sex when you have multiple of the same breed? Is it breed specific? Or just genetics?

Example pictures of 2 I had. Still waiting to determine gender.

It's genetics. Some lines or crosses can be sexed that way but they have to be bred specifically for that for it to be anywhere near accurate. The majority of chickens, and hatchery chicks especially, cannot be feather sexed.

Eta, it also only works within a specific time frame. I want to say it has to be done at 3 days old, but don't quote me on that. Since it's never been an accurate for any of the birds I've owned I never really paid any attention to the details. never really paid

Thank you!

Yea both my Wyandottes (pictured) I believe are pullets at this point. And they’re actually quite different in a few ways.

Yes, this 'method' of sexing hasn't ever worked for my flocks either. I hand raised chicks from a mixed flock (so it's even harder to tell because I like punishing myself) and the biggest Male feathered out the fastest and his brother was the slowest feathering out of my group but both were boys. Up until 4 weeks, the only suggesters (and even these aren't 100% reliable) is comb size (again, breed specific) and red colouring in the comb under 8 weeks (except in Ayam Cemanis due to their black pigmentation). It truly is a guessing game. I tend to watch their personalities too, watching for chest bumping, comb growth and charging. These tend to be the best indicators I have found for sexing young birds (still not 100% though).
