It is possible to find organic soil amendments, which I am ok with using as chicken feed. I am sourcing through Concentrates in Portland, Oregon. They just started a mail order service, which I figure will cost a fortune, but less than buying pre mixed organic feed.
I am using fish meal, crab meal, and kelp added to a two to one mix of field peas to wheat, with oyster shell free choice.
