Where Do Eggs Come From?

Eggs come from birds and some other animals, but the ones we usually eat come from chickens. When a hen lays an egg, it’s starting a new life cycle, even if that egg isn’t fertilised. It’s amazing to think that something so small has its own story starting inside the hen.

What Makes Eggs So Special?

Eggs are more than just food; they are tiny packages full of life and nutrients. Inside each egg, there is a perfect balance of proteins, fats, vitamins, and minerals that help living things grow strong and healthy. It’s this mix that makes eggs truly special and important for both animals and people.

Different Types of Eggs

Eggs come in many different types, and each one has its own story. Here are some interesting scientific facts about the common types of eggs you might find:

Standard White and Brown Eggs – These are the most familiar eggs you see in grocery stores. The colour depends on the hen’s breed, not its nutritional value. Both white and brown eggs are packed with nutrients.
Free-Range Eggs – These eggs come from hens that get to roam outside and peck at bugs and plants. Because of their outdoor life, the eggs often have richer flavours and a bit more nutrition.
Organic Eggs – Organic eggs are laid by hens that eat organic feed without chemicals or pesticides. These eggs are often chosen by people who care about natural farming and healthy food.
Cage-Free Eggs – Cage-free hens live indoors but without cages. They have more space to move around than caged hens, which can change the quality of the eggs they lay.
Omega-3 Enriched Eggs – Some hens are given special diets rich in omega-3 fats, which makes their eggs a good source of these healthy fats. These eggs support brain health for kids and adults alike.
Pasture-Raised Eggs – Hens that live mostly outdoors on pastures lay these eggs. They have access to fresh grass and insects, which can enhance the flavour and nutrient profile.
