Hi, I was talking to my Grandpa who used to have 3000-4000 chickens in the 1940's or so and he said they used to sex a chick by literally squeezing the crap out of it. He doesn't remember the rest though like how to tell. I assume the looked at the crap or how it came out. Has anyone heard of this? Sorry if its kinda sick. lol. Thanks, Justin.
