I get the hemp from a feed warehouse, I get a 50# bag for about $50. It's been steam sterilized for non-germination purposes (stupid laws). I get the sorghum there as well. The sorghum was pricey and I will probably just replace that portion of my feed with milo (which is 0.55/lb) I get everything I can through azure or my local feed warehouse. I prefer organically grown over conventional. I use yellow field peas or yellow split peas. The field peas you can get from a feed warehouse, feed grade; I also get some from Azure when I can. Always whole flax seed as I read the ground can go rancid fast. The buckwheat is from Azure or local feed warehouse, it is easy to grow and the chickens will harvest the seeds right off the plant for you!! I give only small quantities of this because it can make them more sensitive to the sun (in larger amounts). I give them a variety of wheats, whatever I have on hand but mainly red hard winter, white hard spring & soft white wheat. They do enjoy a variety of grains. On a cold morning I will cook them up some five grain cereal...I mix 2 cups of wheat, 2 cups of millet, 2 cups short grain brown rice, 2 cups of oats or barley, 2cups of split peas or lentils; mix it all together and then grab a cup or so of the mix and cook it, I give it a little rinse, drain and feed. (Want to make sure its not too hot). If you have human grade grains, you could have breakfast with them!! Put your rice bran in a porridge mix with some organic corn as a complementary protein.
