Crushed Oyster Shells - Calcium Supplement for Hens

Benefits of Crushed Oyster Shells

100% natural, crushed oyster shells are an excellent source of calcium and minerals for poultry. They ensure an adequate supply of calcium to produce eggs with strong shells, while promoting healthy bones and muscles in your chickens and chicks.

A sturdy shell provides better protection against bacteria and contributes to the safety of your fresh eggs from the coop.

Crushed oyster shells also aid digestion by helping to break down the food your chickens eat, ensuring their metabolism functions properly.

Calcium Intakes for Hens

Laying hens need about 4 to 5 grams of calcium per day, half of which is used to form the eggshell.

Calcium plays a crucial role in the development and health of the skeleton, as well as in the proper functioning of the hen’s overall body: muscle contraction, hormone release, blood clotting, etc. It is also essential for feather renewal during seasonal molting.

Usage and recommendations

To ensure your chickens get enough calcium, it’s best to provide them with oyster shells on a self-service basis. Keep them available in the pen or coop at all times and reduce the amount of feed you give them.

You can mix them directly into your chickens’ daily feed or give them in a separate container.

Note: Although their schedule may vary, hens generally lay eggs at the end of the day, since the final stages of egg production often take place at night.

Hens' needs vary depending on factors such as their breed, age, and the season.
