Flint or insoluble grit. Chickens donât have teeth, apparently, they are very rare, so to grind down their food, they use a strong muscular organ called a gizzard. Chickens pick up grit whilst foraging, which is kept for a while in the gizzard to perform this grinding process.
Because of this they do not need grit the way some other birds do. In fact it can pose a danger to their health. Please note this quote from Avian Web.com: Grit is an important aid in helping certain birds, such as finches, canaries and other passerines, digest food - but this does NOT apply to parrots.
