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 Amercan-made recyclable bags.

No more cracked eggs here
At the end of the day, I want to make sure our eggshells stay thick and do not crack, and this product does the trick! I’ve always used oyster shells, but I love the sourcing transparency of this and my birds eat it just like they do oyster shells, so consider me a convert!

Increased Shell Thickness and Body Weight
This product helped my girls (my laying chickens) increase their shell thickness and body weight.

Great product plus it’s made in the USA
I’ve been using the Shell and Bone Builder for a few weeks now. I’ve noticed a drastic improvement in their health of my birds eggs. I have had a few birds that consistently laid pliable shells (I have 200+birds). I have not had this issue since using this!!!
Andrea –
Great to mix in with layer feed!
We’ve been feeding Shell & Bone Builder to our birds for about a week and I really feel like their eggshells are thicker since they started eating it. We usually mix it with their feed, and we will continue to give them the calcium while they are laying eggs.

Thick eggshells!
I needed some calcium for my hens and this sounds safer than oyster shells, so I wanted to give it a try. The size is great and easy for them to eat, and I plan to give it to my hens weekly.

Great for my flock
My birds love this stuff! They eat it when they need the calcium and i love having a safe option I can use to support them (and our eggs).
