Actually, the last time I looked into it, if you grow 2 acres of corn and 1 acre of soy, and feed it to chickens, you get out a similar number of calories (and more protein?) as 3 acres of soy.

Soy is pretty good, but corn is insane.

		Corn produces something like 15M calories per acre, soybeans like 6-8. When you feed those 36M calories to chickens, you get back 12M calories of chicken, which is actually less than 6 x 3 = 18M calories for the soybeans, so I'm misremembering something (maybe it's just an equivalent amount of protein? maybe chicken feed is a 3:1 corn:soy ratio?) or was just wrong.
