There are organized people out there that want to end all ownership of animals. They like to put out videos vilifying farmers who have livestock to rally the public against animal ownership.. So you must take that sort of video with a great deal of skepticism and thought and double check what you see with an unbiased source.
Think about it. It is not actually that bad. A sharp blow to the head or neck would kill a chick instantly. IF the chicks are indeed going into a grinder, the blades would be whirling really fast. The chick would immediately receive a blow to the head or spine that would kill it. It would be extremely fast.
The makers of that sort of video want you to equate it to yourself being slowly fed into a grinder, one limb at a time. It's not the same thing at all.
I've seen the equipment used to break necks on unhealthy chicks (and probably excess chicks) so I am a bit doubtful about the "grind them up alive" idea. Large poultry farms are all inspected and they all have laws they must follow, and if chicks are really being put through a grinder, it is an approved method of euthanasia.
