Found a local health food store here (Mama Jeans) has the ingredients for making my own organic whole grain corn/soy free feed if I wish. Comes to $1.70 a pound even with the spendy trendy stuff like the chia or black sesame. That's not bad for the few chickens I have, and worth it to me. Here's what I think I'll use, adapted slightly from Garden Betty website, and very similar to other recipes I've seen:
5 pounds oat groats, 4 pounds of BOSS, 4 pounds of hard red wheat berries, 2 pounds white wheat, 2 pounds millet, 2 pounds kamut, 1 pound green lentils, 1 pound flax seeds, 1/2 pound white sesame, 1/4 pound chia or black sesame, 1/4 pound of kelp granules.
I can lessen the oats and increase the wheat if the yolks seem a little light colored, or tinker as I need to I guess. Any suggestions about what I should drop or add and why are always welcome. It paid to go local this time, rather than trying to buy in such a huge bulk that I'd take forever to use it up. Small time operation here. Just 12 now, and will be down to 6 when my neighbor gets his coop built and can take his girls off my hands.
