If you can get some like minded people together, most mills will run batches of just a few tons. Figure out your ration and run it by a nutritionist (they have very knowledgeable staff at Fertrells, btw) and then talk to different mills about your ration. You might be quite surprised. And in fact, you might also suggest that offering such a ration would be good for business ;)

This is how one of only a couple mills operating in our state manages to corner that niche market. Our ration has a small amount of kelp, local oats and barley, fish meal for protien, and a smidgen of grit included. I add the kitchen trimmings/veggies of course, but also plain cracked corn and free choice grit and oyster shell. I cannot let them free range until fall since they'd wipe out my garden, haha

My egg production is very good, better than most and I have a coming set of replacement layers that are way bigger than anyone else's-I presume due to the feed management?

The "soy is in every pelleted ration" is maybe true, I do know that those horse people battling Cushings' have a real hard time because beet pulp is in everything, just about.
