Rabbits are one of the worst forms of protein as it takes more feed to create protein than other animals.
Chickens have the best feed-protein ratio, better than insects even.
Sheep, goat, and cattle convert non-edible grass grown on non-arable land into protein. Basically, time + sun + rain -> protein. It's also being discovered that ruminants are critical for turning marginal farm land into productive grain land.
Both of the above are totally available, practically for free, to anyone with a little bit of land. There's no reason we should be buying protein from the store at all.
