What is a chickens beak made up of?

A chicken's beak, like all bird beaks, is made of a tough, keratinized material called keratin. This is the same material that makes up human hair and nails.

Here's a breakdown:

* Keratin: A fibrous protein that forms the outer layer of the beak. It's strong, durable, and water-resistant, perfect for pecking, scratching, and grabbing food.

* Bone: A beak also has a bony core called the rhamphotheca. This provides the underlying structure and support.

* Nerves: The beak is sensitive to touch and temperature thanks to a network of nerves.

So, the beak is a complex structure that combines tough keratin with a bone core and sensitive nerves, enabling chickens to perform a variety of important tasks!
