Oyster Shell Grit - Fine

Fine Oystershell Grit is the ground up shells of oysters. Fine oyster shell grit for birds can be fed on its own or mixed with seed. There are two distinct types of grit: Insoluble - such as flints, are taken into the gizzard by the bird and used to grind down the food with a strong muscular action. Soluble - such as Oyster shell are a source of calcium which is vital for the production of strong shells. It is digested by the bird to ensure it has sufficient levels of calcium within its body to produce high quality, strong-shelled eggs. Remember - All laying hens need a constant source of both types of grit.
