ANATOMY

Detailed explanation-1: -From the esophagus food moves to the crop, an expandable storage compartment located at the base of the chicken’s neck, where it can remain for up to 12 hours.

Detailed explanation-2: -Chickens don’t have teeth and they’re prey animals, so they can’t waste much time chewing. Instead, they swallow food quickly and store it away in their crop, a pouch-like organ meant solely for storage. It’s the first pit stop for her layer feed. Within the crop, very little digestion occurs.

Detailed explanation-3: -Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Detailed explanation-4: -The proventriculus is the true stomach of the bird from which hydrochloric acid and pepsin (an enzyme) is secreted to aid in digestion. The gizzard is the oval organ composed of two pairs of thick red muscles. These muscles are extremely strong and are used to grind or crush the food particles.

Detailed explanation-5: -Information. The gizzard is the mechanical stomach of a bird. It is located just after the true or glandular stomach in the gastrointestinal system. Since poultry have no teeth and swallow feed whole, this muscular organ, sometimes called hen’s teeth, mechanically grinds and mixes the bird’s feed.
