Chick sexing thru behavior?

[The Moonshiner]

when you come up on a hen fast, push down on their back, brush their back end

Why you be doing all that?

I've googled all the different ways to sex chicks and none of them have ever referenced the behavioral squat that hens do.
I was petting the backs of my 9 day old chicks and notice some of them already do that squat thing when I rub them. Wings out, funny chirp and throwing that butt right back!
Is this a good way to determine pullets and cockerels?

I didn't tell you to do that. Shoulda added "Don't try this at home if you been drinkin" heh

No, it sounded like it was something you did or do. I was a little cringed by it.

It appears threads that discuss unconventional chicken sexing techniques like "brush their back end"(not their vent) is not your cup of tea. My sincerest condolences for you. Personally I find vent sexing day old chicks a little more cringe worthy than "doin all that". I just finished vent sexing 75+ chicks today. What a chore. No job for someone with a weak stomach that's for sure. Again.. My sincerest condolences for you. Peace Out.
