Availability and types
The chicken egg is an ingredient you can buy almost everywhere and all year round. Chickens have been laying eggs for thousands of years – domestic chickens originally descend from wild Asian junglefowl. Today chickens are kept in many countries because eggs are nutritious, inexpensive and versatile. Therefore you constantly find eggs at the supermarket, since farms lay throughout the year. In winter chickens sometimes lay a little less, but stocks and farm planning ensure we still get enough eggs.
Where do these eggs come from exactly? It varies:
- From the local farm: often fresh eggs sold around towns come from here. Many people buy there because they know the animals or the family.
- From the supermarket: large retailers supply eggs from different regions or countries. This stabilizes supply.
- From industry: in some regions eggs are produced in very large quantities and then packaged and distributed.
There are different kinds and labels of eggs. The most important things in simple words:
- Sizes: eggs come in sizes like S, M, L and XL. It's like shoes – a larger egg has more content.
- Shell color: some eggs are white, others brown or even greenish. The color depends on the hen breed, not the taste. It's like cars: different colors, same function.
- Housing systems: the carton often shows a number (0–3). This number indicates how the hens were kept:
- 0 – Organic: hens have more space, outdoor access and organic feed.
-
- 1 – Free-range: hens can go outside, they have space and outdoor access.
-
- 2 – Barn: hens live in a barn, but not in cages.
-
- 3 – Caged: hens live in cages. Many countries have rules about cage size.
- Special eggs: some eggs have special properties:
- Omega‑3 eggs: hens received feed that increases healthy omega‑3 fat. It's like a "plus" of certain nutrients.
-
- Double yolk: sometimes a hen lays an egg with two yolks – it's rare and amusing, but edible.
- Processed forms: eggs are not only available fresh:
- Boiled eggs (hard or soft boiled) are ready to eat.
-
- Pasteurized liquid eggs or egg powder are often used in the food industry because they last longer.
When shopping you can check the label: it states where the eggs come from, what size they are and the housing system. If you want to know how the hens are kept, look for terms like Organic or Free-range. Overall eggs are a very available and diverse ingredient – from simple supermarket eggs to special organic farm eggs.
