Oh, I know about that. So much that in fact I don't like the american sweet corn variety and much prefer ordinary maize in my plate. In fact, you can't make a decent tortilla unless it's made from said maize, and not the more refined variety. As a side note, maize has a tendency to grow a blueish-black fungus on it called huitlacoche (you guys call it corn smut). Down here it's a delicacy and it's used as a filling in empanadas. It has an awful look, but it's quite delicious.Our normal chicken feed was cracked 'feed' field corn or small kernel Maize.
