Oyster Shell Layer Grade (50 lb bag)

Pacific Pearl Oyster Shell is a trusted, natural calcium supplement for poultry, used by over 30 million laying hens daily across the West Coast. This durable 50 lb bag of coarse, feed-grade oyster shells for chickens is specially formulated to support hens, ducks, and other egg-laying birds by promoting strong eggs and healthier laying cycles.

The slow-digesting granules provide a steady release of calcium carbonate, supporting both eggshell strength and skeletal health. Perfect for use alongside layer feed or as part of your flock’s grit and oyster shells blend.

Key Benefits

• Promotes laying eggs with strong, healthy shells
• Reduces soft shells, breakage, and undergrade eggs
• Encourages long, productive laying cycles
• Can be fed free choice or mixed into feed (3–5% of total ration)
• Packaged in a sturdy bag—ideal for small or large flocks

Feeding Directions

Offer Pacific Pearl Oyster Shell in a separate feeder to allow hens to self-regulate their intake, or mix 3–5% into the total feed ration at the onset of lay.

Why Calcium Matters

Laying poultry need a reliable source of calcium carbonate to produce strong eggs and maintain bone density. Without enough calcium, hens may experience shell deformities, brittle bones, and reduced productivity. This calcium supplement is a natural, slow-release alternative to synthetic additives—making it a reliable choice for supporting optimal egg production.
