I was just discussing this last night with DH, as I have been spending increasing amounts of time thinking about the best way to stop feeding corn, as it is impossible to know whether one is really getting non-GMO. He suggests we plant some next year, bless his heart, and we probably will try, but could never water enough to feed the flock through the year, at least not in any substantial percentage. I have handmixed scratch using cracked corn, whole wheat and whole oats, and they like it okay but don't scramble for it the way I would expect them to, so I'm sure the cracked corn is GMO and I probably won't add it again. Will try some BOSS, not sure what else. They get FF every morning, except this weekend it's supposed to drop into the teens overnight so I may cook them some cracked wheat and steel cut oats for breakfast
