Greatness starts on day one. Purina® Start & Grow® Medicated chicken feed contains amprolium (not an antibiotic) to aid in the prevention of coccidiosis. Our feed gives your chicks a strong start and enhances early hen development. Raise chicks from day one to laying age (18-20 weeks) with feed that supports their digestive health and immune function – and aids in the protection against coccidiosis where immunity is not desired.
If your birds have not been vaccinated for coccidiosis or if you're unsure of their vaccination status, we recommend feeding your birds Purina® Start & Grow® Medicated.
Also available as non-medicated feed.
