SHELL & BONE BUILDER - All Natural Calcium Supplement for Laying Hens to Support Strong Eggshells and Bone Health

At Perdue, we know chickens. We’ve been caring for them for over 100 years! In fact, the backyard flock of our founders, Pearl and Arthur Perdue, started it all. To this day, we remain dedicated to raising strong, healthy, and happy birds through science and innovation.

If your poultry are laying eggs, they need a calcium supplement. Calcium is an essential nutrient for backyard flocks that supports strong eggshells to keep the eggs we eat safe and strengthens bones to keep your birds healthy. But here’s the thing – not all calcium is created equal. Shell & Bone Builder® provides a large and consistent form of calcium for poultry and is harvested and packaged here in the USA to guarantee safety and quality. Go beyond the typical calcium source for your backyard flock with Shell & Bone Builder®.

Feature Benefits:

• FOR LAYING POULTRY: Shell & Bone Builder® is an all-natural, premium calcium supplement for laying poultry 18+ weeks of age. Calcium supports strong eggshells and bone health in chickens, ducks, turkeys, and quail.

• THE RIGHT PARTICLE SIZE: Shell & Bone Builder® provides a large, consistent size of calcium carbonate to laying hens. This slow-release form of calcium is highly digestible and allows a hen to process and absorb it when it’s needed most – overnight when the eggshell is being formed.

• STRONGER EGGSHELLS FOR SAFER EGGS: When it comes to eggshells, stronger means safer. The eggshell is a natural barrier protecting the eggs we eat from harmful contaminants, and calcium is the essential nutrient needed for eggshell formation. Shell & Bone Builder® particles support overnight eggshell formation first, and the remaining calcium goes straight to the bones for stronger, healthier birds.

• NOT ALL CALCIUM IS CREATED EQUAL: Limestone is a natural mineral mined from the earth. Once it hits or goes over 38% calcium, it is called calcium carbonate. The calcium carbonate in Shell & Bone Builder® guarantees the highest level of calcium without heavy metal or bacterial contamination that can occur with oyster shells.

• 100% USA SUPPLY CHAIN: Shell & Bone Builder® is a safer, top-quality calcium source for laying poultry harvested in the American Midwest and packaged in Arkansas using American-made recyclable bags.

• SAFE FOR ALL POULTRY SPECIES: Shell & Bone Builder® is for laying hens 18+ weeks of age and can be fed in one of three ways: 1) free choice in a separate container, 2) sprinkle ½ cup in the coop twice weekly, or 3) mix 1lb Shell & Bone Builder® with 20lb layer feed
