Candling is a process used to check the fertility of a budgie's egg and monitor the development of an embryo inside the egg. It involves inspecting the exterior of the egg with a flashlight or torch to determine the quality of the shell and the fertility of the egg. The best time to candle budgie eggs is after five days of incubation when veins start to appear inside the egg.

What You'll Learn
How to candle budgie eggs
Candling is a process in which a breeder checks that the eggs their bird has laid are fertile or not. It is a way of inspecting the exterior of the egg with a flashlight or torch to determine the quality of the shell. It also provides information about the fertility of the egg, and the formation of the germinal disc and air sac.
To candle budgie eggs, you can start after four to five days of incubation and continue every few days. Make sure the room is dark, and hold a candle or small penlight flashlight at the larger end of the egg, where the air sac is located. You can gently rotate the egg to study the blood vessel growth and the embryo’s development. You should be able to see red veins on the inside of the shell and a small dark spot, which will be the embryo. If the egg is clear, it is probably not fertile. You can also tell by the egg colour; fertile eggs will be bright white, while infertile eggs will be a dull white.
If you do not see the lines (veins) or the dark spot of the embryo inside after 10 days, you can probably throw the egg away. Before you open any nest box to remove or check the eggs, always tap on the box door lightly so the hen knows you are there and you do not frighten her. It is also important to wash your hands before touching the eggs to prevent pathogens from penetrating the shell.
Candling may become a necessity in some situations. For example, if the egg is pushed out of the nest by its mother, or if your bird is young and you want to confirm that everything about the egg’s interiors is in good condition.

When to candle budgie eggs
Candling is a process used to check the fertility of a budgie's eggs and monitor the development of the embryo. It is an easy way to supervise the chick's safety and ensure a healthy junior. The process involves inspecting the exterior of the egg with a flashlight or torch to determine the quality of the shell and the fertility of the egg.
You can start candling budgie eggs after five days of incubation and continue every few days. It is best to wash your hands before handling the eggs to prevent any pathogens from penetrating the eggshell. The room should be dark for successful candling. Hold the egg about one foot away from your eyes, with the candle or flashlight very close behind the egg. You should be able to see the veins and embryo inside a healthy egg.
If you do not see the veins or embryo after 10 days, the egg is likely not viable. However, sometimes it is difficult to observe the embryo, especially if the eggshell is thick or dark. In such cases, you may need to rely on other indicators, such as the colour of the egg, as fertile eggs tend to be bright white, while infertile eggs are dull white.
It is important to note that candling is not always necessary unless there are specific concerns, such as an egg being pushed out of the nest by the mother or a young bird laying an egg. Additionally, while candling can provide valuable information, it is crucial not to disrupt the hen's eggs too frequently during the critical first few days of incubation, as this is the most important time for embryo growth.

What candling looks like
Candling is a process that allows breeders to check the fertility of their birds' eggs and monitor the development of the embryo inside. It is an easy way to check on the health of the egg and the safety of the chick.
To candle an egg, you need to create darkness in the room and use a small, bright torchlight, like a penlight or Mag light, to illuminate the egg from within. Hold the egg in front of you, about a foot away at eye height, and hold the torch very close behind the egg. You should be able to see red veins on the inside of the shell and a small dark spot, which is the embryo. If the egg is clear, it is likely not fertile. Fertile eggs are bright white, while infertile eggs are dull white. If there are no red veins or a dark spot after 10 days, the egg is likely dead.
You can also candle eggs without removing them from the egg box when the hen is absent. Just ensure you have a clear view of the egg and wear gloves. Wash your hands before touching the eggs to prevent pathogens from penetrating the shell.
The process of candling can begin after five days of incubation, and you can continue every few days after that. The bigger the chick grows, the darker the egg becomes. As the chick develops, you will be able to see it form a circle inside the egg with its egg tooth, a small pointy tool located at the end of its beak.

What candling reveals
Candling is a process that allows breeders to check the fertility of eggs and monitor the development of the embryo inside. This process can be performed after five days of incubation, and every few days after that.
To candle an egg, one must hold a candle or small flashlight at the larger end of the egg, where the air sac is located. The room should be dark for successful candling. The light will expose the interior of the egg, revealing red veins and a small dark spot, which indicate a healthy, fertile egg. If the egg is infertile, it will appear clear, with only the shadow of the yolk visible.
Candling can also reveal the quality of the egg shell, which is important as cracks in the shell can allow bacteria to enter during incubation, leading to infection and the premature death of the embryo.
In some situations, candling may become a necessity. For example, if the egg is pushed out of the nest by the mother, candling can be used to check the condition of the egg's interior. Additionally, if the bird is young, candling can be used to confirm that everything is developing as it should be.

What to do with the information
Candling is a process that allows budgie breeders to check on the fertility and health of their birds' eggs. It involves examining the interior of an egg with a flashlight or torch, usually after five days of incubation. To candle an egg, you must hold it about a foot away from your eyes, with the light source very close behind it, so that you can observe its contents.
If you are having trouble viewing the egg's contents, turn off some lights or move to a darker room. You should also ensure that your hands are clean and dry before handling the eggs, as oil from your fingers can clog the pores in the eggshell and prevent the embryo from getting enough oxygen.
When candling a budgie egg, you are looking for signs of fertility and healthy development. If the egg is fertile, you should see red veins on the inside of the shell and a small dark spot, which is the embryo. The veins may start to become apparent after just three days, but the embryo may not be visible until after a week of incubation, when it will appear as a black patch with spider-like veins flowing out from it. If the egg is infertile, you will only see the shadow of the yolk without any veins or a dark spot. Fertile eggs are bright white, while infertile eggs are dull white.
If you do not see any signs of development after 10 days, the egg is likely not viable. However, it is important to note that some eggs may appear to be behind in development due to the viewing angle or other factors, so it is best not to give up on them until you are sure they are not developing.
Candling is a useful tool for budgie breeders to monitor the development of their birds' eggs and take immediate action if an egg is infertile or damaged. It can also help identify cracked eggs, which are at risk of becoming infected and causing the embryo to die prematurely. While candling can provide valuable information, it is important to minimise disruptions to the hen and her eggs during the critical first few days of incubation.

Frequently asked questions
Candling is a process in which a breeder checks that the eggs their bird laid are fertile or not.
You can candle budgie eggs after five days of incubation and continue to do so every few days.
You will need a small, bright flashlight. Hold the egg about one foot in front of you at eye height. Hold the flashlight very close behind the egg so you are looking through the egg with the flashlight pointing towards you.
If the egg is fertile, you will see red veins on the inside of the shell and a small dark spot, which is the embryo. If the egg is infertile, it will be clear.
Candling is important because it provides insight into what is happening inside the egg before it hatches. It can help you monitor the development of the embryo and remove any infertile eggs.
