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 you check for fertile eggs?
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?
When you crack open the egg, if it's fertile, you'll notice a small white spot on the top of the yolk about 4mm in width. This is called the germinal disc. This is what tells you if the egg has been fertilised. This disc is formed with a single cell from the female and a single sperm from the male.
How do farmers know if a chicken egg is fertilized?
Egg farmers even "candle" eggs, which involves holding them in front of a bright light (or a candle) in a dark room. Fertilized eggs will have dark splotches in them, or might be entirely opaque, depending on the stage of development of the chick.
Can you incubate an unfertilized egg?
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 a cracked egg still incubate?
Eggs with hairline cracks might often not be recognised and will, consequently, be placed in the setter trays and incubated. In cracked eggs, the shell is broken and the underlying membrane is ruptured – leading to dehydration and the death of the embryo.
How can you tell if a bird egg is alive?
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.
How can you tell if a chick is alive in an egg?
You'll see blood pumping through the heart of a tiny, developing embryo if you candle a fertile egg on Day 4. If the embryo dies at this point, you may still see a faint network of blood vessels inside the egg's contents.
How can I test my eggs at home?
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?
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.
What does a bad egg look like when candling?
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 soon can you tell if a chicken egg is fertile?
In reality, eggs with these brown spots are not fertilized and are formed or picked up as a part of the natural egg-creation process. Often mistaken for each other, these spots are actually quite different.
Can you tell if a freshly laid egg is fertilized?
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.
Are brown eggs fertilized?
It's unlikely, but not impossible.
Can refrigerated eggs hatch?
During their exploration of chicken embryology, youth learn that for a chicken to develop from an egg it must be fertilized. Most eggs sold commercially in the grocery store are from poultry farms and have not been fertilized. In fact, laying hens at most commercial farms have never even seen a rooster.
