fertilized vs unfertilized chicken egg

When shopping for chicken eggs, have you ever wondered if these are fertilized or unfertilized eggs?

And will this factor affect how the eggs look and taste?

Don’t worry, you will find out the answer after reading this blog post talking about the differences between fertilized chicken eggs and the unfertilized counterparts to clear up any confusion.

Let’s check it out!

What are fertilized chicken eggs?

Fertilized chicken eggs contain a nucleus of an ovum cell that is merged with the sperm cell.

This allows for genetic material to be present within the egg.

The egg can then be developed into an embryo by a woman’s uterus.

A fertilized chicken egg will have an extra yolk inside.

A fertilized chicken egg can hatch into a baby chicken if being incubated by the mother hen.

Therefore, if the purpose is to produce more chicken, fertilized eggs should receive more care because they contain life.

However, sometimes, they are just consumed as regular eggs without waiting until they hatch.

People will take the fresh eggs from their farm or backyard to sell or eat in a conventional way, such as boiling, frying, scrambling, or being an important ingredient for baking recipes.

It is also said that fertilized eggs contain more nutrients that are needed for the embryo to grow such as protein, iron, phosphorus, magnesium, potassium, and calcium.

And don’t worry if you buy a package of fertilized chicken eggs from a grocery store and they will hatch in your house.

These eggs can only hatch under proper incubation by the hen or an incubator.

It’s better to keep eggs in a cool place like in a fridge to keep them fresh and not hatch.

What are unfertilized chicken eggs?

Generally speaking, every chicken can lay eggs without a male chicken.

And if the hen isn’t mated with a rooster, her eggs are called unfertilized eggs.

Scientifically speaking, unfertilized eggs do not have any genetic material in them and cannot develop into an embryo without another source of genetic material such as the male chicken’s sperm or from other species of the opposite sex.

Moreover, an unfertilized chicken egg cannot hatch.

Therefore, the only use of this kind of egg is for cooking.

Unfertilized chicken eggs work the same way as fertilized eggs in terms of cooking, such as being boiled, scrambled, or fried to serve with some toast or salad for a quick and hearty meal, or used for baking cakes.

What are the differences between fertilized chicken eggs vs unfertilized chicken eggs?

Although fertilized chicken eggs and their unfertilized counterparts might look exactly the same, they actually differ in many ways, as mentioned in the comparison table below:

 ComparisonFertilized chicken eggUnfertilized chicken egg
Where it comes fromFrom a hen that is mated with a roosterLaid by a female chicken by her own without involving any rooster
Interior appearanceThe egg yolk is usually largerThere is likely a white circle present in the egg yolk and small red lines running along the surface of the yolkBigger in size (averagely 50 grams per egg)White or tan and thicker shells
Nutritional contentIt is believed that fertilized chicken eggs are more nutritious because they needed them for growing the embryoNutritious and provide us with many essential nutrients, but seem to be less than fertilized eggs
Shelf lifeShorter and easier to be spoiled Should be kept in the fridgeLonger and can be kept at room temperature

What are the similarities between fertilized chicken eggs vs unfertilized chicken eggs?

Despite some key differences between fertilized chicken eggs and unfertilized chicken eggs, they are basically the same thing when it comes to cooking.

So here are some similarities between these two types of eggs:

1. Fertilized eggs and unfertilized eggs are nutritious

There has been no scientific study showing the difference in the nutritional content between fertilized eggs and unfertilized eggs.

People just believe that since fertilized chicken eggs have the embryo, they need more nutrients to raise and grow it.

Anyway, both kinds of eggs are rich sources of protein, calcium, iron, vitamin A, B-vitamins, phosphorus, magnesium, and many other essential nutrients for our body.

2. Fertilized eggs and unfertilized eggs have the same taste and can be used interchangeably

There is also no difference between the taste of fertilized chicken eggs and their unfertilized counterparts.

Although, there are some people who believe eggs that have been laid from a mated hen will have a tad richer taste.

Due to this similarity, fertilized chicken eggs and unfertilized eggs can be used in numerous ways, such as boiling, frying, scrambling, or acting as an ingredient for baking.

Feel free to use them interchangeably as well because there will be no difference between the taste and look of the chicken eggs when cooking.

There are some misconceptions about fertilized eggs, making them preferable because they taste better and have a higher nutritional value.

However, in fact, there are no significant differences between these two kinds of eggs, especially when you use both of them for cooking.

Choosing between fertilized chicken eggs or unfertilized eggs now comes down to their availability in your local grocery store and their prices.
