What is yolk?

Yolk is like the golden heart inside an egg that gives it its power to grow into a bird or a chicken.

Imagine you have a hard shell around you, that’s like the shell of an egg. Inside, there's a soft part called the white, and then deep in the middle, there's a yellow round ball, that's the yolk.

Think of the yolk as a special food stash for something growing inside the egg. Just like you might save up your favorite snacks to eat when you're playing outside, the yolk holds all the good stuff needed to help a baby bird or chicken grow strong and healthy.

The yolk is full of nutrients, which are like tiny building blocks that help the growing creature inside use its energy well. When the egg starts to hatch, the yolk gives the baby bird or chicken all the food it needs until it can find real food on its own.

So next time you see an egg, remember, the yolk is like a golden treasure hiding inside, ready to help life begin!
