Mixed roasted and boiled grains. Usually contain wheat, oats, & barley. They have been rinsed cooled and bagged and frozen same day. Two pounds each bag (usually more). My chickens LOVE this stuff! It can be thawed and heated (for the younger ones) or just left out for them to peck away at. I wouldn't mind shipping, but am unsure about how to do so with something frozen and was afraid the shipping would be too much.
