The disturbing video below is standard operating procedure when it comes to breeding and processing egg laying hens worldwide. Mercy For Animals writes:
For the nearly 150,000 male chicks who hatch every 24 hours at this Hy-Line facility, their lives begin and end the same day. Grabbed by their fragile wings by workers known as "sexers," who separate males from females, these young animals are callously thrown into chutes and hauled away to their deaths. They are destined to die on day one because they cannot produce eggs and do not grow large or fast enough to be raised profitably for meat. Their lives are cut short when they are dropped into a grinding machine tossed around by a spinning auger before being torn to pieces by a high-pressure macerator.
Over 21 million male chicks meet their fate this way each year at this facility.
For the surviving females, this is the beginning of a life of cruelty and confinement at the hands of the egg industry. Before even leaving the hatchery they will be snapped by their heads into a spinning debeaker a portion of their sensitive beaks removed by a laser. Workers toss and rummage through them before they are placed 100 per crowded box and shipped across the country.
Think about the fact that they're killing off 150K baby chicks every day JUST in this plant. You can go to the Hy-Line website here and see all their locations worldwide.
