Grits are essential in all seed-eating birds’ digestive systems. John Doe Fine Oyster shell Grit is especially suitable to help Diamond Doves, Quails and other seed-eating cage birds digest their foods while also supplying some of the minerals and trace elements essential to good health.
Fine Oystershell Grit is insoluble and acts as a grinding agent in the gizzard to enable complete digestion of all food.
Oyster shell grit is an excellent source of calcium which is soluble and is digested by the bird, enabling her to form strong egg-shells.
A constant supply of Oyster shells prevents her from producing soft or poor quality egg shells. Its slow solubility provides a steady calcium level, ensuring stronger bones and a healthier bird.
We supply Oyta Oystergritmix which dissolves 5-10 times more slowly than other sources of calcium such as limestone.
