Not knowing chickens won't eat oats we figured we would salvage the purchase for ourselves. NOT. They have to be hulled. I found this article on how to do it at home http://www.ehow.com/how_5935440_process-oats-home.html Basically you bake them in the oven and then on a windy day throw them in the air. The hull will blow away and the grain land on the surface (sheet or what ever).
