Chickens need grit because they have no teeth and it helps them digest. Usually grit is stocked and sold by the poultry feed stores. It is found as loose grain sand or small pebbles. When the chickens eat the grit, it is stuck in their gizzard.
When the food passes through the gizzard, it is broken up or crushed into small pieces. This aids for the digestion of the food. Grit acts like teeth in the body of the chicken. Grit is essential part of the meal, even if you are feeding them chicken feed. Free roaming chickens don’t require grit, however, since they get their daily share from the grass and the pebbles on the farm.
Chickens also have vitamin intake requirements. Here are the most crucial vitamins chickens should consume in order to ensure maximum health.
