Chickens eat rocks, stones, and grit to aid in normal digestion. Chickens swallow food whole, as they lack teeth. The gizzard is a muscular stomach that pulverizes unchewed food. Food is ground up easier, faster, and with more energy efficiency in the gizzard with the help of grit. In other words, grit can impact your chicken's health, laying ...Web
