I am trying my best to have my hens on an organic feed when they get to the age where they start laying. I wanted to mix my own and found this recipe that I want to try... 2 parts whole corn (in winter this is increased to 3 or 4 parts) 3 parts soft white wheat 3 parts hard red winter wheat 1 part hulled barley 1 part oat groats 1 part sunflower seeds (in winter this is increased to 2 parts) 1 part millet 1 part kamut 1 part amaranth seeds 1 part split peas 1 part lentils 1 part quinoa 1 part sesame seeds 1/2 part flax seeds 1/2 part kelp granules free choice of granite grit free choice of oyster shell The problem is that I cannot find anywhere that sells all of this organic and in bulk in my area. I am in the Detroit Metro area. Anyone in this area have any ideas? Or is there a supplier online that I can order from? Thanks!
