OK,
What to use other than corn. That is the question. Here is what I am doing so far:
Oats, Wheat (Red Hard/Winter), Black Oil Sunflower seeds, Clover or Alfalfa seeds (All sprouted) Then the mash is chopped apples, or pumkins (Froze in fall from the yard.) This mixed with Alfalfa meal, Fish meal, Black jack molasses and Azomite, . Are all good as far as I can tell. (I use them as primary and then free choice with organic premix which does have corn and soy in it, which they eat very little of. (Trying to eliminate it totally.)
I have an interested in Flax, Quinoa and field peas to work into the mix. Also maybe look at Indian corn or some of the pop corns are not modified.
There are a fair amount of alternatives on this forum and on the net. Corn is really just a cheap filler. Carbs..
Personally, I try and use as little corn and soy as I can, (For me, my family and my chickens).... Way Way to much of both corn and soy in the American diet.
