Does feather sexing actually work?

Hi, I heard feather sexing works but I'm not sure, my week old chick, Sesame has a lot of wing feathers and a few small tail feathers. Apparently this means she's a pullet? I'm not so sure. What do yall think? But anyway this is Sesame.

Pullets may feather in faster than cockerels so in conjunction with other indicators it could help tilt a guess in favor of boy or girl, but by itself it's not an accurate sexing method.

It's genetic. Some breeds/crosses can be feather sexed, others can't.
I just made a orpington x CL crossing that has a dramatic feathering difference between males and females. They're growing combs now so it's confirmed.
Female and male in the pic, notice the tail feathers.
