I understand that each animal slaughtered needs to be done with a special kind of knife and by a shochet. How might an industrial kosher farm operate without the need for an exorbitant amount of employees? Could there be a contraption that holds each animal, and a shochet pulls a level which controls several kosher knives?
To be true, there isn't a 'industrial kosher farmer', each animal has to be killed one by one, the animal cannot be afraid of dying, he cannot see other animals dying (as it would create fear on him). The person who will kill the animal has to do it when the animal is calm and prepared to die.
To kill all animals in a really really kosher way, it is necessary to make a large structure.
Some rabbi like Alon Anava do not eat from this 'industrial kosher seals'
