Literally nobody is mentioning the fact that to own 13 chickens there were 13 roosters that were euthanized as chicks. 50% of chickens are born male. Nobody wants all those roosters. Some dude in a factory is squeezing the chicks and looking up their buttholes to see if they are male or female, then the males are thrown into a meat grinder (literally).

Saying all of that, I would rather eat eggs from chickens that had a half-decent life than those kept in horrible conditions.
