Purina(R) Farm to Flock(R) Harvest Festival(TM) Block is a balanced recipe made with goodies like wheat, barley, milo, sunflower seed, oyster shell, and pumpkin seed. It provides enrichment no matter the season. In the fall, place the harvest flavored Farm to Flock(R) Block outside for birds to peck and encourage natural pecking behavior. In colder weather, the block supplement can be a useful boredom buster, giving birds a place to peck - keeping the flock occupied and less likely to peck one another while in the coop. | Purina Farm Flock Harvest Festival Poultry Feed | Size 20 lbs
