Grit is necessary for the healthy development of a chicken's gizzard. The gizzard aids in digestion, and allows for maximum nutrient benefit from whole grain feeds. Grit comes in various sizes for different birds depending on size and age.
Made up of insoluble crushed quartzite and / or granite, grit remains in the bird's gizzard to help with digestion. Grit is an essential part of your bird's diet and should always be provided, especially if there is no access to small rocks.
If you have bantams or smaller hens, the Cluckin' Good Layer Grit may be too large for their size.
