@Michael_Huntington and I watched Faces of Death, and so now I remember the flapping chicken, hell it even kind of flies for a few seconds.
They also showed how they butcher cows. From A to Z. That was pretty fucking gross. But the guy who talks during the scenes said that the workers told him, after the ’‘novelty’’ wears off, that it becomes routine just like any other job. And novelty was in the movie’s words, I didn’t chose it.
But I don’t think this is how they slaughter cattle anymore. (slashing the throat)
