A: A complete feed, like Layena feed, is important because hens require additional, specific nutrients when they begin laying eggs. We looked to our own backyard flock to fine-tune this feed so it will work best in the backyard poultry environments. If offered many different feedstuffs, chickens may pick and choose (much like children!) and will likely not get the optimal complement of necessary nutrients. One feed that contains everything they need is the best way to ensure proper nutrition. To provide the nutrients your laying hens require, start feeding Purina® Layena® Premium Poultry Feed to hens when they begin laying eggs between ages 18 weeks and 22 weeks.
