Grow Your Own Poultry Feed - In a time of economic constriction, a home poultry flock can contribute to food security — if you’re not totally dependent on purchasing poultry feed to keep it producing. The home flock that makes you more food-independent is the one that is fed, at least partly, from your homestead’s own resources. Fortunately, the natural feeds you can produce in your backyard are what chickens would eat in the wild: green plants, wild seeds and animal foods, such as earthworms and insects — all fresher and more nutritious than anything you can buy in a bag.
