Fertilized Egg: How to Check if a Chicken Egg is Fertilized

Are you curious about whether the eggs you collect from your backyard chickens are fertilized or not? Understanding how to determine if a chicken egg is fertilized can be fascinating for both novice and experienced poultry keepers. In this article, we will explore the various methods and techniques you can use to check if a chicken egg is fertilized, providing you with the knowledge you need to ensure your eggs are exactly what you want them to be.

Understanding Fertilized Eggs

What is a fertilized egg?

A fertilized egg is an egg that has been fertilized by a rooster, containing both the yolk and the embryo. This means that if the egg is incubated, it has the potential to develop into a chick.

How does a chicken egg become fertilized?

In order for a chicken egg to become fertilized, a rooster must mate with a hen. During mating, the rooster transfers sperm to the hen, which fertilizes the egg before it is laid. Once fertilized, the egg will start developing into a chick if it is incubated.

How to identify a fertilized egg

There are a few ways to identify if a chicken egg is fertilized before consuming it. One common method is called "candling", where a bright light is shone through the egg to see if there are any visible signs of development, such as veins or a dark spot. Another method is to crack the egg open and look for a small white spot on the yolk, known as the blastodisc, which indicates that the egg has been fertilized.

Methods to Check if a Chicken Egg is Fertilized

Candling method

One common method to check if a chicken egg is fertilized is by using the candling method. This involves shining a bright light through the egg in a dark room to see if there are any visible signs of development, such as the presence of veins or a dark spot (the embryo). Candling is typically done around day 7-10 after the egg has been laid.

Cracking method

Another way to determine if a chicken egg is fertilized is by simply cracking it open. A fertilized egg will have a small white spot on the yolk known as the germinal disc, which indicates that the egg was fertilized. However, this method is not always reliable as the germinal disc can be difficult to spot, especially in eggs from young hens.

Consulting a professional

If you are unsure about whether an egg is fertilized or not, it is best to consult a professional, such as a veterinarian or a poultry expert. They will be able to provide you with accurate information and guidance on how to properly determine if a chicken egg is fertilized.
