Oops, just noticed you wanted grain only. Well, that may be a problem. Peas and beans have anti-nutritional factors, which is why it is so difficult to balance a chicken ration with the proper protein without using soy. Then, even with soy, you don't have balanced methionine. Alfalfa meal helps...
Why does everyone assume organic means vegetarian? Azure Standard has a non-soy, Non-GMO, with animal protein organic layer, grower and starter feed, all the mixes are less than $28.00 for 50 lobs. If you have drop point in your area, it sounds to me like it's what you're looking for.
