this is why i think chicken is the best meat, no other animal is so easy and normal to literally raise in your backyard, plus they can get a decent amount of their food from bugs and foodscraps
it's entirely feasible for basically everyone with a yard to own chickens and call the butcher when they get too old to lay eggs (or just near death), and this would make eggs basically free and meat very cheap, plus massive quantities of free fertilizer for farmers!
we need to feed them corn and soybeans because people want lots and lots of meat, and that's the best way to get lots and lots of meat.
that's.. kinda why people advocate for eating less meat, so that there won't be such a powerful incentive to turbomaximize meat yields to meet the huge demand..
