I remember when I was a kid my grandma and me would feed the chickens dried corn we'd use our thumbs to break the corn right off the cob and the chickens would eat it up. But, I don't know if that is a thing people do now and I don't know how safe it is. We were just poor country folk and probly only had that to feed them at the time. I don't remember any chickens dying from it though.

i'm not sure what you mean by chopped corn, but my girls LOVE raw corn on the cob. i shuck the corn and tie the cob to a string hanging from a low branch and they have a ball with it. and whole oats are a summertime staple for them.

ceresone, my grandmother used to go to the corn crib and get a few ears of dried corn and husk with her hands on the ground for the chicks and they would come running. I don't believe she ever bought a bag of feed in her life. They lived on bugs and weeds and whatever else they could scratch up, plus the corn in winter.
