This spring I am going to start growing grain in my yard and at a community garden to use for my chicken feed. I was thinking of growing kamut wheat, sorghum, field corn, oats and also sun flowers and soy beans. Are these good grains for chicken feeds and are their any others you can recommend? I was thinking of also doing barley but I thought I remembered reading something on here saying chickens don't like the taste of barley? Can give me an estimate of how many pounds of feed a free range chicken would eat per month or per year?
