Thank you for the info about the Ultra Kibble; I will have to go check that out; I am just starting the FF and right now the bucket has 1 scoop each wild bird seed, milo, rolled barley, wheat and alfalfa cubes, used home made ACV and yogurt to start it; bubbling merrily along. The milo is not that well liked by the big girls and seems a bit big for the chicks, so will probably choose something else when I run out. I'm also currently reading Poultry Feeds and Feeding,maryhysong,
I'm avoiding GM crops and soy in our diets as well as the chickens' diets. For the chickens, this has meant avoiding corn and soy since I can't find/afford to order organic corn. I am new to chickens, but am going to tell you what I'm doing so you can research it and see if it'll work for you (logistically, but also whether it will provide what you want for your flock)...
I ferment with ACV:
3 parts whole wheat
3 parts whole oats
2-3 parts milo/sorghum
1 part BOSS (too much?)
1 part Ultra Kibble
You can search for threads about the Ultra Kibble here on BYC. It was originally created as a supplement for jungle fowl being raised in captivity (zoos, etc) and can be applied to chickens. I order it through amazon with free shipping and a bag lasts a long time b/c you need so little. From what I understand, a tiny bit of UK provides all the nutrition that they need in a slow-digesting pellet, but they need other foods in their diet to feel full and satisfied so I use the whole grains. The UK has some corn and there is the possibility of GMO there, but I feel like I'm doing the best I can to create a 'complete' feed with all the nutrition they need and still have the *least* amount or none of the things I don't want. Here is the owner/creators answer about GMO in UK:

One of the big things they keep coming back to is feeding milk, especially buttermilk, for fattening chickens but also for raising chicks, mixed into the mash. When I kept dairy goats all the off milk, cheese whey and such went to the chickens; had the hardest eggshells in the country! When we had a lot more small mixed farms this would have been the norm; so many head of cows, sell so much cream and butter, feed skim milk to the pigs and buttermilk to them and the chickens. Each operations waste was feed stock for the next operation.
