The Purina® Flock Block® Supplement is a treat for laying hens and mixed poultry flocks. Made from whole grains, it provides nutrients and enrichment no matter the season. In the summer it encourages natural pecking behavior, and in colder weather it’s a useful boredom buster – giving birds a place to peck besides each other.

Available in a 25lb block.
