Suffocation of Male Chicks in Garbage Bags
Suffocation of male chicks inside plastic garbage bags will of course sound insane to anyone who is not familiar with the egg industry.
But in hatcheries that breed chicks for egg farms, the killing of male chicks is the daily routine. Because male chicks do not lay eggs, they can't produce profit and are seen as a waste product.
From that point, each hatchery choose its own way to kill the chicks. Among the common methods are grinding up the chicks alive in a macerator, and suffocating them.
