Features & Benefits
Research-proven feed
Purina® has been conducting poultry research for nearly a century. We have a flock of backyard birds at the Purina Animal Nutrition Center to help our nutritionists, feed formulators and flock caregivers evaluate our feeds before we put them on the market.
Added calcium
When complete layer feeds aren’t accessible or during times of stress for your birds, Purina® Oyster Shell provides an excellent source of supplemental calcium.
