Natural Grit is a mixture of silex, red stone and oyster shells. 

It does not contain any appetite-enhancing substances. The various components are essential for an optimum digestion and to increase the effectiveness of the grinding of the grains in the gizzard so that all nourishing substances can be perfectly assimilated.

The red brick particles and shell fragments provide the necessary minerals and trace-elements.

The Natural Grit is heated to over 200°C to eliminate all harmful micro-organisms.
