when the chicks are born in hatcheries, they are separated based on their sex. The males are put on one conveyor belt and the females are placed on another. The conveyor belt for the males then usually goes to one of two places: a gas chamber where they are gassed to death or an industrial macerator that grinds them up alive. This happens in all systems of egg farming, including free range and organic. In some countries, male chicks are alternatively suffocated in bin bags or crushed to death.
