Eggs - Facts for Kids

History & Origins

Some of our ancient ancestors collected and ate wild bird eggs millions of years ago — long before there were farms, houses, or fire.

Chickens were most likely first domesticated in Southeast Asia about 3,000–4,000 years ago — long after people had already learned to farm rice, build villages, and use fire.

Long ago, Romans cooked eggs with milk and honey — something like a very old egg-pancake.

In some parts of medieval Europe, people sometimes paid rent with eggs or poultry instead of money — especially if they kept hens.

The Easter egg hunt tradition started over 400 years ago in Germany, where parents would hide eggs in gardens for children to find!

The first chocolate eggs were made in France and Germany in the early 1800s, combining two of the world's most beloved foods!

Ancient Chinese families would give red-dyed eggs to celebrate a baby's first month of life!

The word ‘egg’ in English comes from an old Norse word ‘egg’ — the language of the Vikings — which shows how long humans have been talking about this amazing food!

By the late 1800s in America, eggs became more common for breakfast — especially as more families had chickens and eggs were easier to get.

Science & Making

An eggshell has between about 7,000 and 17,000 tiny pores — tiny holes too small to see without a magnifying glass — which help air and moisture move in and out.

When you cook an egg, its proteins change from liquid to solid in a process called denaturation – it's like magic in your pan!

A fresh egg will sink in water, while an older egg floats because air builds up inside the shell over time!

The color of an egg's shell depends on the breed of chicken – it doesn't affect the taste or nutrition!

An egg white turns from clear to white when cooked because heat changes its protein structure – like turning invisible ink visible!

The yellow part of an egg (the yolk) contains special proteins that make cakes fluffy and cookies chewy!

Eggs can foam up to 8 times their original volume when whipped, creating enough bubbles to make a meringue as tall as your hand!

Eggs go bad faster at room temperature than in the fridge — leaving an egg out a day might make it age nearly as much as a whole week of fridge time!

When you boil an egg, the water will be around 100 °C — not hotter. Eggs don’t crack because the water is ‘too hot,’ but because they get a sudden jolt of heat or pressure inside from expanding air.

Ingredients & Nutrition

A big egg gives you about 6 to 7 grams of protein — not bad for something small! It’s almost like half of an ounce of chicken in protein strength.

Eggs are one of the few foods that naturally contain Vitamin D, which helps make our bones strong!

The yolk holds most of an egg’s vitamins and minerals — including all the fat‑soluble vitamins (A, D, E, K) — while the white is mostly protein.

Egg whites are made up of 90% water and 10% protein – that's why they're a favorite food of athletes!

One egg has all nine essential amino acids our bodies need but can't make on their own!

The golden color of egg yolks comes from special plant pigments in chicken feed called carotenoids!

A big egg gives you around 6–7 grams of protein and about 70 calories — not bad at all! For many people, that’s around one‑tenth of the average daily protein you need.

Eggs contain choline, a special nutrient that helps our brains develop and stay healthy!

The protein in one egg is more easily used by our bodies than the protein in most other foods!

Sometimes, eggs from chickens that roam outdoors and eat a natural diet have more vitamin E and healthy omega‑3 fats — but that only happens if the chickens eat the right foods.
