Purina Mills® Scratch Grains SunFresh® Grains is a natural blend of high-quality natural grains designed to be fed free-choice to adult chickens, ducks, geese and turkeys to encourage the natural pecking and feeding instincts. Note that Scratch Grains is a grain supplement, not a complete feed. If too much is fed, it will dilute the feed intake of complete feeds such as Start & Grow®, Layena® and Flock Raiser®, reducing the bird’s nutritional intake and overall performance. Purina Mills® Scratch Grains SunFresh® Grains should not comprise more than 10% of the birds’ overall diet.
