ANTONII [103]

Answer:

How does the digestive system of poultry vary from other animals?
Vinvika [58]

Answer:

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.
