First off, the gizzard is a muscular organ found in the digestive tract of birds, reptiles, and even some fish. Think of it as nature’s built-in food processor. Birds don’t have teeth, right? So their gizzard does the chewing for them.
It’s a tough, gristly pouch that grinds up seeds, bugs, and grit. Imagine a rock tumbler in your belly, and you’re getting close. The gizzard is basically a stomach with attitude.
