Key Benefits

• Promotes laying eggs with strong, healthy shells

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.
