It was a matter of squeezing the chick to get the egg yolk out, the egg yolk that they lived on after they hatched. It would be eighteen days in the incubator, and three days in the hatching compartment. And in order for the chick to look nice and yellow and bright, they have to use formaldehyde mixed in some other charcoal. And when you walked in when the formaldehyde was not only for keeping it germ-free, but it also turned the white chicken yellowish color. There's something about a pure white chicken that didn't look just right, however, a little baby chicken, one day old, that had a yellow color, fluffed out, looked a lot better to the buying public, apparently. And oh, I'm not sure how long it took for us to be adept at it, but we, with our thumb and forefinger on the left hand, we opened the vent, identified on the rim whether it was male or female, and sexed, that's what sexing was about.
