Six Interesting Egg Facts Worth Knowing

Did you realize that approximately 75 billion eggs are produced in America annually?

Eggs have a variety of uses, such as food, decoration, cake, and even solving common household problems, such as slugs and stained mugs!

Here are six fascinating facts about eggs that you should be aware of.

Chicken eggs come in various colors, not just white and brown.

The egg’s color depends on the breed of chicken that laid it.

Eggs can be blue, blue-green, reddish-brown, or even speckled.

You can determine the age of an egg by placing it in water.

Simply fill a bowl with water and add the eggs.

If the egg sinks to the bottom, it’s fresh, and if it floats to the top, it’s not.

Around 75 billion eggs are produced in the United States each year.

This accounts for about ten percent of the world’s total!

However, China is the largest egg producer, with over 390 billion eggs produced each year, accounting for roughly half of the world’s egg supply.

Edible eggs are not just laid by chickens.

Although chickens are the most common egg-laying birds, don’t forget about ducks, emus, geese, turkeys, ostriches, and quails.

When hard-boiling eggs, it’s best to use ones that are not too fresh.

Fresh eggs have a tendency to stick to the shell, making them more difficult to peel once hard-boiled.

Eggs can be utilized to aid in the treatment of wounds.

The membrane surrounding the egg’s white can assist in the treatment of fevers, minor wounds, bruising, scarring, sunburns, and splinter removal.

1. How can you tell if an egg is fresh?

Fresh eggs have a thick, cloudy white and a firm yolk that stands up. To test freshness, you can place the egg in a bowl of water. If it sinks to the bottom and lays flat on its side, it’s very fresh. If it stands up on one end, it’s still good to eat but not as fresh. If it floats to the top, it’s spoiled and should be discarded.

2. Are brown eggs more nutritious than white eggs?

No, the color of the eggshell has no impact on its nutritional value. The color difference comes from the breed of the chicken–brown eggs come from breeds with brown feathers, while white eggs come from breeds with white feathers. The nutritional content of an egg is determined by the chicken’s diet and living conditions.

3. What is the difference between cage-free and free-range eggs?

Cage-free eggs come from hens that are not confined to small cages, but may still be kept indoors in a large barn or warehouse. Free-range eggs come from hens that have access to the outdoors, and can roam and forage for food. Free-range eggs are often considered more humane and may have slightly higher nutritional value due to the hens’ varied diet.

4. Can you eat eggs past their expiration date?

It’s best to follow the expiration date on the egg carton. However, eggs can often be safely eaten up to a week after the expiration date if they are stored properly in the refrigerator. If you’re unsure, you can perform the same water test as for freshness (see question 1) to see if the egg is still good.

5. Why do some eggs have double yolks?

Double yolks occur when a hen releases two yolks into the same shell. This is more common in young hens whose reproductive systems are still developing, or in hens that have been selectively bred to lay larger eggs. Double yolk eggs are safe to eat, but may be slightly higher in cholesterol due to the extra yolk.
