Hens store small fragments of stone in their gizzards to grind the food they eat. Poultry on open range can pick up the grit required, but when they are housed intensively indoors it is essential to supply them with a source of insoluble grit. Limestone or crushed seashells are not useful for this purpose as they have no sharp edges for grinding feed. The feeding of insoluble grit to growing chickens up to six weeks of age is not necessary.
