Product Description:

For backyard chickens, laying hens, and poultry owners, maintaining strong eggshells and healthy bones is essential. Without proper calcium supplementation, hens may produce thin or fragile eggs, increasing the risk of egg breakage and calcium deficiency. Our crushed oyster shells provide a natural, digestible source of calcium that improves eggshell quality, supports bone development, and enhances overall chicken health.
100% Natural & Safe – A pure, natural source of calcium for poultry care.
Supports Laying Hens – Ideal for chickens, ducks, and other egg-laying birds.
Stronger Eggshells – Reduces eggshell breakage and improves hatchability.
Essential for Bone Health – Helps prevent calcium deficiencies in chickens.
Sustainable – A great addition to your homesteading essentials.
Can I use this with my Pullets? Yes! Our oyster shell and coral calcium blend is perfect for pullets and provides calcium for growth.
Is this the same as grit? No. Grit aids digestion, while oyster shells provide calcium for eggshells.
How often should I provide oyster shells? Keep available at all times for laying hens to consume as needed.
