Supplement your laying birds' feed for stronger shells and healthier birds with Purina Oyster Shell Premium Poultry Supplement. This egg-laying poultry supplement helps support eggshell integrity by providing a source of calcium for laying birds. This poultry feed is recommended for any egg-laying bird like chickens and turkeys.

• 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.
• Purina Oyster Shell is made for a mixed flock of egg-laying chickens and turkeys
• Caution: Use only as directed; if an excessive amount of grit accumulates in the feed troughs, reduce the level added
