I believed eggs were not fertilized, no?

The issue here is the eggs that are fertilized, to create the laying hens. The males are a waste product, and are discarded.

The only way to determine the gender of a chick (until very recently!) is a visual check done after the animal is born.

Huh never thought about that. Thanks!
