Candling is a technique used to shine a bright light into an egg to see its interior. It is used to identify whether the embryo is developing as it should and to remove non-viable eggs. During candling, a bad egg can be identified by a lack of development compared to other eggs, a vague ring inside the egg, a distinct blood spot, and little to no veins. Bad eggs can also be identified by their smell, oozing substance, and strange colouring. It is important to identify bad eggs early to ensure the health of the remaining developing eggs and to prevent contamination.

What You'll Learn
A bad egg will have a very nasty smell
Egg candling is a process where a bright light is shone into an egg to see its inside. It is a great way to identify whether the embryo is developing as it should and to remove non-viable eggs.
In addition to candling, there are other ways to identify a bad egg. One way is to check for cracks in the shell. Eggs with cracked shells should be considered bad eggs as they are prone to bacterial contamination. Another way is to check for strange colouring, such as pink spots, which could be a sign of mould. Freshly laid eggs that are bad will also appear yellowish when candled and will not have any veins or shadows.
It is important to identify and remove bad eggs from the incubator as soon as possible. This is because they can quickly explode and contaminate the healthy eggs and the incubator.

A red blood ring around the embryo means it's bad
A red blood ring around the embryo means its bad. This is an indication that the embryo has died and should be removed from the incubator immediately. The blood vessels that had begun to form have started to decompose, and instead of remaining attached to the embryo, they float in the yolk and form a circle.
Candling an egg involves shining a bright light into it to see its contents. This process is done to identify whether the embryo is developing as it should and to remove non-viable eggs. It is important to note that the temperature of the egg should be maintained during candling to avoid damaging the embryo.
When an egg is developing normally, you will see a system of blood vessels spreading evenly across the surface of the yolk, resembling a spider's web. However, when there is a blood ring, you will observe a dark line running around the circumference of the egg.
To identify a bad egg, you can also look for other signs such as a vague ring inside the egg with little to no veins, a distinct blood spot with minimal veins, or a lack of development compared to other eggs. It is crucial to spot bad eggs early to ensure the health of the remaining developing eggs.
Additionally, bad eggs may start to emit a very unpleasant odour and may even begin to ooze a honey or light brown-coloured substance. These eggs must be removed from the incubator immediately as they may explode and contaminate the healthy eggs.

A bad egg may ooze a honey/light brown substance
Egg candling is a necessary part of the incubation process that involves shining a bright light into an egg to see its inside. It helps identify whether the embryo is developing as it should and allows for the removal of non-viable eggs.
To prevent this, eggs should be clean before being placed in the incubator. Bacteria can be transferred to eggs if one hasn't washed their hands. Cracked eggs are also likely to become infected, causing premature embryo death.
Candling eggs is a straightforward process and can be done using a household torch. It is recommended to candle eggs in a dark room to get a better view.

A bad egg will have no veins or shadows
Candling is a necessary part of the incubation process, helping identify whether the embryo is developing as it should. It involves shining a bright light into an egg to see inside it.
If you are having trouble viewing the contents of an egg, turn out some lights or go into a dark room. You can candle your eggs every day if you like, but after day three, you should see something. By day eight, you can see the embryo wiggling and kicking in its egg.
Other signs of a bad egg include a vague ring inside the egg and little or no veins, a distinct blood spot with little or no veins, and a lack of development compared to the rest of the eggs. Bad eggs will also have a very nasty smell.

Bad eggs will mould and shrivel within the first week
Egg candling is a process where a bright light is shone into an egg to see its inside. It is used to identify whether the embryo is developing as it should, and to remove non-viable eggs. Non-viable eggs are those that are infertile or have died prematurely. Rotten eggs can explode, contaminating other fertile eggs.
Candling eggs can help identify bad eggs early on. Indicators of bad eggs include a vague ring inside the egg and a distinct blood spot with little or no veins. Lack of development compared to other eggs in the hatch is another indicator, though this could be due to the viewing angle or other factors.
Outside of candling, bad eggs can be identified by their smell, texture, and colour. A bad egg will have a sour or mildewy smell, and its yolk will be dull and yellowish. The egg whites will run out lifelessly onto a plate. If the egg white has a green or iridescent look, it may have harmful bacteria.

Frequently asked questions
To candle an egg, shine a bright light into it and observe its contents. This can be done with a small penlight or a powerful flashlight. The darker the room, the easier it will be to see inside the egg.
A bad egg may have a red ring of blood around the embryo, indicating that the embryo has died. It may also have a vague ring with little to no veins, or a very distinct blood spot. If the egg is clear after 10 days, or if there is a lack of development compared to other eggs, it may be a bad egg.
If you find a bad egg, remove it from the incubator immediately. Rotten eggs can explode and contaminate the other eggs.
