Candling is a process used to check the fertility of eggs by illuminating them with a bright light in a dark room. While candling brown eggs, one might encounter some difficulties due to the darker shell of the egg, which blocks more light. However, by day eight, you should be able to see the eye and body of the developing chick even within a brown egg. Using a high-powered flashlight in a dark room can help illuminate the egg better. Some people also use their iPhone flashlights or the flashlight feature on their cell phones.

What You'll Learn
Candling brown eggs requires a dark room
Candling brown eggs can be challenging due to their darker shell colour, which blocks more light and makes it harder to see inside. To overcome this issue, it is recommended to candle brown eggs in a dark room to reduce external light sources and improve visibility.
The process of candling involves examining eggs to assess fertility and embryo development. It is typically done by shining a bright light through the eggs in a dark environment. For brown eggs, the darkness of the room is crucial to successful candling. By eliminating external light, one can better observe the interior of the egg and identify signs of viability.
In a dark room, a high-powered flashlight or a dedicated egg candler can be used to illuminate the eggs effectively. The light source should be bright enough to penetrate the brown shell and create a visible glow, allowing the observer to detect the presence of an embryo and assess its development.
To enhance the candling process for brown eggs in a dark room, it is recommended to adjust the egg's orientation. Turning the egg with the air sac upwards or pointing downwards can provide a better view of the interior. Additionally, blocking excess light with your hand or using a card to slide over the light between eggs can improve visibility and reduce glare.
By following these suggestions, individuals can improve their ability to candle brown eggs in a dark room. It is important to give your eyes time to adjust to the darkness and be patient as it can be more challenging to assess brown eggs compared to lighter-shelled eggs.

Use a high-powered light source
Candling brown eggs can be challenging due to their darker shell colour, which blocks more light and makes it harder to see inside. However, using a high-powered light source can improve visibility and aid in detecting the signs of a viable embryo.
One option for a high-powered light source is a flashlight. A standard flashlight may not provide enough illumination, but a high-powered variant, such as one used for work inspections, can make a significant difference. For example, a flashlight with a 10,000 lumen beam output on the highest setting will illuminate the egg much better than a typical egg candling flashlight, which may have a lower output of around 250 lumens.
When using a high-powered flashlight, it is important to be mindful of the heat generated by the light. Keep the flashlight at a safe distance from the eggs to avoid cooking them. Additionally, consider using a stand or a flat surface to hold the flashlight steady during the candling process, reducing discomfort and allowing you to focus on examining the eggs.
To further enhance the visibility when using a high-powered light source, create a dark environment by candling in a dimly lit or dark room. This will prevent external light from interfering with your observation. Additionally, you can cup your hand around the egg and the light source to minimise light leakage and improve your ability to detect details within the egg.
While using a high-powered light source improves visibility, it is still important to give your eyes time to adjust to the darkness, especially when candling brown eggs. This will enhance your ability to discern the details within the egg, such as the presence of red veins, which indicate a healthy and developing embryo.

Brown eggs are harder to candle than white eggs
Candling is the process of determining the condition of an egg's air cell, yolk, and white by observing its inside using a light source. It is done in a darkened room, with the egg held in a slanting position with the large end against the hole in the candler. The egg is then grasped by the small end and turned quickly to the right or left to observe the contents.
To candle brown eggs effectively, it is crucial to minimise light leakage. One method is to cup your hand around the egg and the flashlight to prevent light from escaping. Using a powerful flashlight can also help penetrate the shell of brown eggs. Some people have found success with inexpensive LED flashlights, while others suggest using old film strip projectors or mag lights. Additionally, it is important to ensure that the room is as dark as possible, as even a small amount of ambient light can interfere with the candling process.
It is worth noting that some people have found blue or green eggs to be even more challenging to candle than brown eggs. Olive Egger eggs, in particular, are known to be extremely difficult due to the combination of the dark brown and blue coating.

Give your eyes time to adjust to the dark
When candling brown eggs, it is important to give your eyes time to adjust to the dark. Candling involves examining eggs to check for fertility and embryo development. Brown eggs can be more challenging to candle due to their darker shells, which block more light.
To give your eyes time to adjust to the dark when candling brown eggs, it is recommended to perform the process in a dark room or during the night when it is completely dark outside. By reducing external light sources, your eyes will gradually become more sensitive to the subtle lighting conditions required for candling.
It is also suggested to use a focused light source, such as a high-powered flashlight or the flashlight feature on a cell phone, for candling brown eggs. This helps concentrate the light on the egg and prevents excess light from escaping into the room. You can cup your hand around the flashlight and the egg to block out light leakage. Additionally, using a thick cardboard lip around the bottom of the light source can further minimize light leakage.
While candling brown eggs, it is important to be patient and allow your eyes to adjust to the darkness. This may take a few seconds, and you might need to carefully shift the orientation of the egg to get a clear view. By day eight of incubation, you should be able to observe the eye and body of the developing chick, even within a brown egg. However, it is important to note that as the chicks get larger, it can become more challenging to see inside brown eggs.
In summary, when candling brown eggs, give your eyes time to adjust to the dark by performing the process in a dark environment and using a focused light source. Be patient and carefully manipulate the egg to get the best view. By day eight, you should be able to observe the developing embryo, but as the chicks grow, it may become more difficult to visualize them clearly.

Number your eggs to keep notes and learn for next time
Candling brown eggs can be tricky, and it can be hard to determine whether an egg is a "winner, quitter or yolker". It is recommended that you number your eggs with a pencil mark on the shell and keep notes so that you can learn for next time. This way, you can track the progress of each egg and make more informed decisions about removing any eggs that might be dead.
One issue with candling brown eggs is that the shell colour makes it harder to see inside the egg, especially as the chick gets larger. This means that it can be difficult to assess whether an egg is fertile or not. By numbering your eggs, you can keep track of which eggs you have candled and make notes on what you observed. For example, you might note whether you saw any signs of life, such as the eye and body of the developing chick, or red veins spreading out inside the egg.
Additionally, numbering your eggs can help you to identify any patterns or trends in the candling process. For instance, you might notice that certain eggs from the same batch or with similar characteristics are more likely to be fertile. This information can be useful for future candling sessions, helping you to make more accurate assessments and improve your hatch rate.
Furthermore, keeping detailed notes can help you to identify any issues or problems that may arise during the candling process. For example, you might notice that certain eggs are not developing as expected or that there are signs of contamination. By having a record of your observations, you can take appropriate action, such as removing a potentially bad egg or adjusting your incubator settings, to ensure the health and safety of your eggs.
Overall, numbering your eggs and keeping detailed notes is a valuable practice that can help you to improve your candling skills and increase your chances of success in hatching healthy chicks. It allows you to track the progress of individual eggs, identify patterns, and address any issues that may arise. So, don't be discouraged if you're new to candling brown eggs – with a little organisation and note-taking, you'll be well on your way to becoming an expert in no time!
