Candling an egg is a straightforward process that can be done at home to check an egg's freshness and viability. It involves shining a bright light through the eggshell to illuminate its contents. This process can reveal hairline cracks, blood spots, and the presence of an embryo. By candling an egg, you can determine whether it is progressing normally or if there are any issues that might lead to hatching difficulties. The process is simple and inexpensive, and it can be performed using a small ultra-bright torch or a homemade egg candler.

|---|---|
| Definition | Candling is the process of shining a bright light into an egg to see inside it. |
| Purpose | Candling is used to check the freshness of an egg, identify cracks, and determine if an egg is fertilized. |
| Timing | Eggs can be candled as early as day 3 or 4, but veins and other indicators of progress may not be visible until later. It is recommended to avoid candling during the last 3 days of a hatch unless necessary. |
| Frequency | Eggs can be candled daily, but it is not recommended as it can influence growth and development through repeated interruptions. |
| Duration | Eggs can be kept out of the incubator for up to 30 minutes during candling but should be returned as soon as possible. |
| Equipment | A small, powerful light source such as a torch, flashlight, or a specialized egg candler can be used. Homemade candlers can also be made using a light bulb and a metal can. |
| Room Conditions | Candling should be performed in a dark room to better visualize the egg contents. |
| Egg Preparation | Wash and dry the eggs before candling to remove any dirt or soil. |
| Technique | Place the egg on top of the light source or hold the light source against the egg, ensuring the light is concentrated on the egg. Roll the egg slowly to inspect all sides. |
| Indicators of Freshness | Clear signs of development, such as veins, blood vessels, and a wiggling embryo, indicate a fresh egg. A vague ring, lack of veins, distinct blood spots, and lack of development may indicate an egg has gone bad. |
| Indicators of Cracks | Cracked or "iffy" eggs may have hairline fractures or wrinkles and should be discarded to prevent bacterial contamination. |

What You'll Learn
What to look for
When candling an egg, you are looking for any signs of cracks, blood spots, or other undesirable contents. You are also checking for the embryo's development and viability.
To begin, ensure you are in a dark room—the darker, the better. You will need a bright light source, such as a small ultra-bright torch, a powerful light, or an LED bulb. If using a torch, cup your hand around the light end to concentrate the light and create a good seal. Place the egg on a table-top unit or hold it in your hand. If using a table-top unit, roll the egg slowly and look for any imperfections, especially at the top and pointy end of the egg.
You should start to see something by day three, with veins becoming apparent. By day eight, you may be able to see the embryo wiggling and kicking. As the hatch progresses, the air pocket in the egg should get larger, and the egg will darken as it fills with the bird.
If you notice a vague ring inside the egg and little or no veins, a distinct blood spot, or a lack of development compared to other eggs, these are signs that the egg may be bad.

Candling equipment
Today, there are two main types of candling equipment: a torch with a rubber seal around the end, and a table-top unit with a place to sit the egg. A small ultra-bright torch is sufficient for candling, and a good seal can be made by using your hand between the egg and the torch. Most modern candlers use light-emitting diodes (LEDs) instead of electric bulbs because LEDs produce bright white light without generating much heat. It is important to note that normal LED torches with batteries tend to dim over time, so rechargeable options are preferable to maintain brightness.
For those who prefer a hands-free option, there are table-top units that can be placed on a surface, with the egg placed on top for candling. These units are especially useful for candling smaller eggs, as they provide a stable platform and eliminate the need to hold both the egg and the light source.
It is also possible to build a homemade egg candler using a metal can, a light socket, cardboard, a toilet paper roll, and a light bulb. This DIY option can provide efficient illumination for candling, but it is important to ensure the light bulb wattage is appropriate to avoid overheating and to provide sufficient light for accurate inspection.

How to candle
Candling is a process used to determine the freshness of an egg. It involves shining a bright light through an egg to see inside it. The process is called candling because it was traditionally done with a candle. Today, people use small, powerful electric lights, such as torches or specialised egg candlers.
To candle an egg, you will need a light source and a dark room. The darker the room, the better, as it will be easier to see the egg's contents. You can use a small ultra-bright torch, cupping your hand around the light end to concentrate the light on the egg. Alternatively, you can use a homemade egg candler, which can be made from a metal can, a light socket, cardboard, a toilet paper roll and a lightbulb. Place the egg on top of the candler and slowly roll it around, looking for imperfections.
Before candling, it is important to wash and dry the eggs. Washing them can help to identify cracked eggs, which cannot be candled as they will not survive the process. It is also important to ensure that your hands are clean and dry, as oil from your fingers can clog the pores in the eggshell and prevent the embryo from getting oxygen.
When candling an egg, you are looking for several indicators of progress or problems. From day three or four, veins may start to appear, and these will continue to grow and spread. By day eight, you may be able to see the chick moving inside the egg. As the hatch progresses, the air pocket in the egg should get larger, and the egg will darken as it fills with the bird.
It is important not to candle eggs too frequently, as this can influence growth and development. However, candling can be useful for identifying cracked eggs, which can become infected and cause the embryo to die prematurely. It can also be used to identify non-viable eggs, such as those that are infertile or have died early, removing the risk of them rotting and exploding.

When to candle
Candling is a process used to check the freshness and viability of eggs. It involves shining a bright light through the eggshell to illuminate its contents. The term comes from the traditional method of using a candle as a light source.
So, when should you candle an egg? Well, candling is primarily used during incubation to check for cracks, blood spots, and other signs of infection or non-viability. It can also be used to identify fertile eggs and monitor embryo development. Therefore, the best time to candle an egg is before and during the incubation process.
Before incubation, candling can help identify any cracks or deformities in the eggshell that could allow bacteria to enter and cause infection. Eggs with these imperfections should be discarded. This initial candling process ensures that only intact and viable eggs are selected for incubation.
During incubation, candling can be performed periodically to monitor the development of the embryo. Veins and blood vessels are good indicators of progress, and by day 8, you should be able to see the embryo wiggling and kicking. However, it is recommended to avoid candling during the last 3 days of incubation unless there is a specific reason to do so.
It is also important to note that candling should not be done daily, as repeated interruptions can influence the growth and development of the embryo. Additionally, eggs should not be left out of the incubator for longer than 30 minutes at a time, and it is crucial to maintain the temperature of the egg during the candling process.
In summary, the best time to candle an egg for freshness is before and during incubation, with periodic checks to monitor embryo development. By following these guidelines, you can ensure the viability and progress of your incubating eggs while minimizing any potential disruptions to their growth.

What candling achieves
Candling is a simple method used to check if an egg is fertile and developing properly. It involves shining a bright light through the egg to see what's going on inside without cracking it open. The process is straightforward, and you can even use a household torch. However, it helps to have an idea of what you're looking for inside the egg.
Candling achieves several things. Firstly, it allows you to identify fertile eggs by looking for a small dark spot (the embryo) with red veins branching out and a visible air sac. You might even see some movement. Infertile eggs, on the other hand, will appear clear inside with no veins or dark spots. Secondly, candling helps to remove non-viable eggs, which can become rotten and potentially explode, contaminating other fertile eggs. By removing these eggs, you prevent contamination and save space in your incubator.
Additionally, candling can help you spot hairline cracks in eggs, which can allow bacteria to enter and cause infections that lead to premature embryo death. During the candling process, you can also identify other undesirable contents, such as blood spots, and double yolks, which rarely hatch successfully.
Finally, candling provides a way to track the progress of egg development. By numbering each egg and jotting down your observations, you can easily monitor the growth of the embryo and quickly spot any eggs that are not progressing as expected. This helps you manage your hatch more effectively and prevent potential issues.
