Unearthed Premium Oyster Shell Calcium Supplement for Poultry – 46lb Bulk Bag – USA-Sourced, Feed-Grade Oyster Shells for Strong Eggshells, Healthy Chickens, Ducks & Game Birds

Give your flock the foundation they need to thrive with Unearthed Premium Coastline Calcium & Poultry Shells. Crafted from pure oyster shells collected along the U.S. coastline, our feed-grade granules provide a rich, natural source of calcium that laying hens crave and need to produce strong, healthy eggs. Unlike generic grit, our finely crushed shells dissolve more readily in the bird’s gizzard, ensuring maximum mineral uptake for optimal shell formation, stronger bones, and better overall metabolism. Whether you raise backyard chickens, heritage breeds, or game birds, regular access to our oyster shell supplement helps prevent brittle shells and supports consistent laying performance. Packaged in our most cost efficient 46 lb bag, Unearthed Coastline Calcium & Poultry Shells stay dry and ready to serve day after day. Simply offer free-choice in a feeder or mix into your standard ration to keep your flock—and your eggs—at their best. Trust in USA-sourced quality and elevate your poultry nutrition with Unearthed.
