How does the chicken digestive system work?
The food trickles from the crop into the bird’s stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth. From the gizzard, food passes into the small intestine, where nutrients are absorbed.
