Domesticated animals depend on their owners for many basic needs: shelter, warmth, protection from predators, water, and of course, food. In order to stay healthy and productive, chickens require a diet that properly balances several essential nutrients.
This is partly because they have been selectively bred over the centuries for egg and meat production.1 This diet requires a fairly involved process of blending various grains and other ingredients. While you could literally make your own chicken feed from “scratch" (pun intended), this can be challenging. Many chicken owners prefer to use a commercially produced feed designed to provide a healthy and well-rounded diet for their flock. This is known as a “complete" feed, and there are several different variations available.
