How is chicken digested in the body?

Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

Do chickens have a cecum?

Digestive tract: Chickens have a pancreas, liver, and intestines, which pretty much do the same things as they do in humans. The digestive tract layout differs, though, when you get to the cecum. The plural of cecum is ceca, which is useful to know, because birds have two.
