Essential Calcium for Laying Hens
Oyster Shell Layer Grade (50 lb bag) is a natural, dependable solution for supporting the health and productivity of laying hens. Made from high-quality calcium carbonate and oyster shell, this product offers both a vital calcium supplement and a digestible grit source. When provided free choice, hens are able to self-regulate their intake, promoting stronger eggshells and aiding digestion. This makes it especially beneficial for large flocks where consistent nutrition is key to optimal egg production.
Perfect for Large Flocks
Coastal Brand Poultry Shell is well-suited for poultry keepers looking to maintain healthy layers. Its coarse texture ensures gradual digestion, allowing birds to absorb the calcium steadily over time. The bulk 50 lb bag is an economical choice for those with larger-scale operations or multiple coops, providing a reliable supply that supports consistent laying throughout the season.
Garden Benefits Beyond the Coop
In addition to poultry use, this feed-grade calcium carbonate also offers valuable benefits in the garden. When applied as a soil amendment, it helps improve drainage, reduce compaction, and balance pH levels. The high calcium content not only corrects deficiencies but also enhances nitrogen uptake, promoting healthier, more productive plants. As an added bonus, a layer of crushed oyster shell around garden beds can help deter pests like snails, slugs, and voles.
Versatile and Natural
Whether you’re raising laying hens or enriching your soil, this bulk poultry oyster shell delivers lasting value. Its dual purpose makes it a practical and essential addition to any homestead or farm.

Awesome, great calcium source for my chickens.
I mix this with the scratch and the girls eat it up. The eggs are very big and strong. Easy to store in a bin and just toss out to the girls.
My hens eat this when they need it. So it lasts forever. Good Deal.
