How to tell if a egg is fertile

Did you know you can determine if an egg is fertile or not by looking at the germ spot? The germ spot is the white spot on the yolk. The non-fertile germ spot contains only the female's cells and looks like a solid white spot. In a fertile egg the germ spot contains both the female and male cells.

Did you know you can determine if an egg is fertile or not by looking at the germ spot? The germ spot is the white spot on the yolk. The non-fertile germ spot contains only the female's cells and looks like a solid white spot. In a fertile egg the germ spot contains both the female and male cells.

How do farmers know if a chicken egg is fertilized?

Candling involves holding the egg up to a bright light source, such as a flashlight, and examining the inside of the egg for signs of development. Fertilized eggs will have a small, white spot called a blastodisc or germinal disc on the yolk, which will develop into an embryo if the egg is incubated.

How do you tell if an egg is fertile with a flashlight?

This is called candling the eggs. This step normally takes place during the 9th day of incubation. We use a Brinsea machine to candle the eggs. This allows you to pop the egg on the stand, cover it over with the lid and look through the eye piece to see if there is any fertilisation and development of the egg.

How do you check for fertile eggs?

Before incubation begins, the only way to tell if an egg is fertilized is to crack it open and look at the blastodisc on the yolk. It will look like a bullseye. An unfertilized egg will have a whitish spot there, but no bullseye ring.

Can you tell if a freshly laid egg is fertile?

If you plan to incubate your eggs, it's essential to determine whether the eggs are fertilized or not. Many novice chicken keepers have learned that placing unfertilized eggs in an incubator leads to an unpleasant, stinky mess. Unfertilized or “bad eggs” create a gas buildup, leading to messy egg explosions.

Can you incubate an unfertilized egg?

If you do choose some eggs to incubate, by around day four - if the eggs are fertile - you should be able to see veining and spidering through the shell when you candle it using an egg candler or flashlight. What is this? Only then does a fertilized egg really start to look different than a non-fertile egg.

How soon can you tell if a chicken egg is fertile?

Fertilized eggs are fine to eat, in fact some people claim they healthier than unfertilized eggs, although we've never seen any data supporting that. (Let's be honest; if the fertile egg is fresh and unincubated, you're going to have the addition of just half a cell.)

Is it safe to eat fertilized chicken eggs?

If you crack it open, a fertile egg can be identified by a small white circle on the yolk, that has a 'bullseye' like shape - i.e. one small white circle, with another white ring on the outside of it. This is created by a cluster of cells that, if incubated, will hopefully develop into a baby chick.

How do you tell if an egg has a chick inside?

The closer the embryo gets to day 21, the more blood vessels and structures you may recognize (such as the beak and feet). Quitters — When embryos stop growing, we call them "quitters." You will see a thin, blood ring around the yolk.

What does a quitter egg look like?

If you can't see any defined shapes, it appears solid, or all you can see is an air cell, discard that egg because it's likely gone bad. Likewise, if cracks in the shell are visible when candling, trash it.

Can you candle eggs with a phone flashlight?

You take a bright light turn off any other lights so it's dark and hold the egg right in the light source. You'll be able to see the blood vessels and embryo inside it there is one and it will move if it's alive.

What does a bad egg look like when candling?

Storage time

Storing eggs for at least three days helps prepare them for incubation; however, fresh and stored eggs should not be set together. It is best to incubate eggs within 7 to 10 days of their being laid. Hatchability decreases rapidly when eggs are stored for more than 10 days.


How can you tell if a bird egg is alive?

The freshness of the eggs will be important. If they have been refrigerated for too long they may not be viable. Move them to an incubator and wait. There was some indication on the discussion board that the store-bought eggs take longer to hatch and that the chicks are not as vigorous.

How can I test my eggs at home?

It's unlikely, but not impossible. Most commercial egg farms have strictly all-female flocks because male chickens aren't needed for egg production and aren't suitable for meat either (chickens raised for meat are a different breed).
