| How a Chicken Eats Since they have no teeth, chickens eat and digest food in a three-stage process, each of which can have its associated problems. When a chicken eats, the food it swallows is first stored in its crop, a pouch at the bottom of its neck. Here the food is stored and softened by water, which is one of the primary reasons your chicken must have access to fresh water when feeding. Once the food is softened it is moved by muscles along the oesophagus to the chicken’s stomach. The first part of the stomach mixes the food with stomach acid and pepsin (a digestive enzyme) which helps break down the food. The food then passes into the gizzard, a muscular organ with rough ridges all over the inside, which breaks down the food further using ingested grit. (So, again, that’s why your chickens must have access to clean grit.)
