There are many alternatives to commercial chicken (and other livestock) feed for the homesteader, such as weeds (duckweed, dandelion, etc), grass and ryegrass, leftover or unuseable plants from your garden, wheat sprout, buckwheat, chickpeas, etc., unsellable vegetable and fruits from your local grocer or small farmer next door, apple trees, dogwood, cherry, and rasberries, pulp from your local veggie/fruit juice bar, bugs and worms from the compost pile, etc. and whatever other edible plants grow in your area. You may not find enough to feed our entire coop entirely out of your harvest, but it will definetely and significantly cut on your feed cost.
