Not all pigs and chickens are "factory farmed" but most are. And unlike cows, the term is relatively meaningful and descriptive when applied to the way those are raised. Bro heard about how pigs and chickens get raised in tiny cages never seeing the light of day then assumed that's how it works for cows too, which he now realizes isn't the case because I shamed him into looking it up.
I agree pigs are raised in abominable conditions.
