Oyster Shell is a premium source of calcium for building stronger egg shells.

Provide to laying hens around 20+ weeks of age.

Oyster Shell is rocks with nothing added.

Specifically, 100% natural limestone. Oyster Shell is a blend of fine and coarse untreated calcium carbonate (CaCO) mined from limestone.

Fine particles provide an immediate calcium supply while coarse particles provide a slower, steady calcium release. A mix of fine and coarse provides a consistent calcium release into the hen’s bloodstream overnight providing strong eggs and stronger bones.

How does the subscription work?

Subscribers save 5% on every order, forever! Choose frequency (weekly, monthly, quarterly) —whatever floats your coop. Change frequency & quantity or cancel at any time.

Is this suitable for ducks, geese & waterfowl?

Yes! They love it.

Why do my feed orders look a little different?

100% of ingredients are Certified Organic & Certified Non-GMO so much like organic apples at the grocery store, grain size & color vary a little. All ingredients are exactly the same each time we mill but the color & size may look a little different. If you’d like uniformity of color, mash or pellet is the way to go as the grains are finely ground but whole grains may look a little different - as is mother nature's way.
