What should I look for when candling eggs? To determine if an egg is fertile, look for a network of white blood vessels. The embryo is shown as a black outline in the middle of the blood arteries. You may even see the embryo’s black eyes or a small movement. Both of these characteristics indicate that the egg is a winner.
Does candling eggs harm them? And candling your eggs will not hurt them. In the same way that the mother would leave the nest for a little period each day, it is safe to remove the eggs from the incubator for the few times you will be candling them. As moisture evaporates from the egg during incubation, the air sac size should grow.

How can you tell whether a chick inside an egg is alive?
On Day 4, if you candle a fertilized egg, you will see blood pulsing through the growing embryo’s heart. If the embryo dies at this stage, a faint network of blood arteries may still be seen inside the egg’s contents. A dying embryo at this stage will have a big, black eye.
How can you know if an egg will not hatch?
When a fertilized egg is ‘candled,’ tiny veins resembling spiderwebs will emerge within the shell. Unfertilized eggs will look transparent and should be removed from the incubator immediately. Every third or fourth day, fertilized eggs are examined to see whether they are still viable.
How can you determine whether an egg has been fertilized?
If the egg is viable, there will be a 4mm wide white patch on the top of the yolk when you split it open. The term for this is the germinal disc. This indicates whether or not the egg has been fertilized. A single cell from the female and a single sperm from the male combine to make this disc.
What does the presence of a blood ring in an egg indicate?
A blood ring within an egg indicates that it was viable and started to develop, but perished during the early stages of incubation. The blood stored inside embryonic vessels spills out, forming a ring immediately under the shell.
What does an unfertilized egg look like?
As seen in the image above, an unfertilized egg will have a white spot, but lack the concentric bulls-eye rings. These rings of the bullseye (below) are the sole distinguishable difference between a viable egg and an egg that is not fertile.
How many times should chicken eggs be candled?

How long may fertilized eggs remain viable in the absence of heat?
Up to 18 hours of embryo survival at temperatures below 90°F has been documented. After the power loss, you should continue to incubate the eggs and examine them 4 to 6 days later for additional growth or indications of life.
Is it OK to assist a chick out of its shell?

What happens if eggs fail to hatch within 21 days?
Don’t lose hope if there are still unhatched eggs on day 21. There is a chance that timing or temperature went somewhat incorrect, so let the eggs to mature until Day 23.

We suggest disposing of these eggs, dead young, and/or nest materials (e.g., when cleaning out a nest box) in a location where they will not attract insects to the nest area.
Can I open the incubator during incubation?
When hatching begins and optimal incubator conditions are reached, the incubator should not be opened until all chicks have hatched and are ready to be transferred to the brooder.
Can a fertilized egg be determined without shattering it?
You can determine whether or not the egg you just split open for breakfast is fertilized. Examine the egg for the germinal disc, a floating white speck above the yolk’s surface. The germinal disk of a sterile egg is completely white and includes solely the hen’s cells.
Can unfertilized eggs produce offspring?
Article content. You may be certain, Mark Diacono, author of The Chicken & Eggs River Cottage Handbook, told The Guardian, “You are not going to open a package of eggs, break them, and a chick will fall out.” Typically, supermarket eggs (of any kind) are unfertilized and so incapable of hatching.
How can one distinguish between fertilized and unfertilized eggs?
