Grain is a weak point in our work developing strong local food systems.
How about if we help build a sustainable system for animal feed? Find and support organic grain growers, or at least those who don't grow patented seed. I am growing a bunch of dent corn for the chickens; I believe they are clever enough to get the seeds off the cob and enjoy their time spent doing so.
And of course, free range chickens require less purchased food.
I know people who growing wheat and rye for flour, and there are organic edamame seed available for family use which can be fed to the critters as well. I suspect that cover crops such as rye could be left to hard seed stage and harvested, leaving the straw. It would require timing, but as farmers we depend on that in many matters.
