Why Buy OYSTER SHELL

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

Specifically, 100% natural limestone. Oyster Shell is a blend of fine & 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.

Eggshells are 94-97% calcium carbonate. Oyster shell is an organic, natural way to give chickens the calcium boost needed to produce strong eggshells that will not break.
