Candling is a method used to check if an egg is fertile and developing properly. It involves shining a bright light through the egg in a darkened room to see the embryo and the spider-like veins. Typically, veins may start to be apparent by day 3, with some sources stating that spider-like veins can be seen around day 6-7. By day 7, the veins should be visible, and by day 14, the veins will be visible beneath the chick.

What You'll Learn
Veins should be visible by day 3
When candling eggs, it is important to know what to look for and when to check during incubation. Veins should be visible by day 3, but this may vary depending on the egg's fertility and development.
On day 3, you may begin to see veins appearing around a dark spot, indicating a fertile egg. These spider-like veins will continue to grow and spread, providing essential nutrients to the developing embryo. By day 6 or 7, the veins should be more prominent and can be seen stretching out into the yolk. However, it is important to note that some eggs may develop at a slower pace, and the lack of visible veins by day 3 does not necessarily indicate an infertile egg.
To enhance your candling experience, ensure you are working in a darkened room with minimal light interference. This will help you better observe the contents of the egg. Additionally, practice clean handling by washing your hands before candling to prevent the transfer of bacteria to the eggs.
It is recommended to candle eggs every day to monitor their progress. However, it is crucial to return the eggs to the incubator as soon as possible, ideally within 30 minutes, to maintain stable temperature and humidity levels. Remember, the development of veins is a positive sign, and their continued growth is a strong indicator of a healthy and progressing embryo.
In summary, visible veins by day 3 is a good indicator of a fertile egg, but it is important to be patient and continue observing over the next few days. Consistent candling, coupled with proper handling and incubation practices, will increase your chances of successful hatching.

By day 7, spider-like veins should be visible
When candling eggs, it is normal to see spider-like veins by day 7. This is a sign that the egg is viable and fertile. The embryo will be in the middle, and the spider-like veins will be stretching out into the yolk, supplying nutrients.
However, it is important to note that not all eggs will show veins by day 7. Some eggs may only have one or two small lines of veins, while others may have a more developed \"spider web\" of veins. The visibility of veins can also depend on the colour of the eggshells, the angle of candling, and the type of incubator used.
If you are having trouble seeing the veins, try turning off some lights or moving to a darker room. You can also try rotating the egg to get a better view. If you still don't see any veins, it is best to wait another day or two before trying again.
It is also important to note that the absence of veins does not necessarily mean that the egg is not developing. Some eggs may be \"quitters\", which means that the embryo has started to develop and then died. In this case, the contents of the egg may appear cloudy and move around. If you are unsure, you can leave the egg until day 10-12 and candle it again to see if there are any changes.
By day 14, a healthy chick should take up most of the egg, and the veins will be less visible. If the egg still looks clear or hasn't changed since day 7, it is likely that it is not viable and should be removed.

No veins by day 14 could indicate the chick stopped developing
Candling is a method used to check if an egg is fertile and developing properly. It involves illuminating the egg with a candler in a darkened room. By day 3, veins may start to be apparent. By day 7, a viable, fertile egg will have an embryo in the middle, and spider-like veins stretching out into the yolk, supplying nutrients.
By day 14, a healthy chick should be taking up most of the space inside the egg, and the egg will be darker with less light passing through. It is harder to see inside the egg at this stage. If there is no change by day 14, this could indicate that the chick stopped developing. The egg may be clear with no dark spot or blood vessels, or there may be a very distinct blood spot with little or no veins.
It is important to maintain the correct humidity during the incubation period. If the humidity is too low, the chick can get shrink-wrapped and be unable to move; if it is too high, the chick can drown in the excess moisture. Bacteria can also be an issue, transferred to eggs via unwashed hands or an unsterilized incubator.
To avoid these issues, it is recommended to wash your hands before and after handling eggs, and to avoid candling after day 18, as days 19-21 are when chicks are positioning themselves for the hatch and should not be disturbed.

Lack of movement doesn't always indicate veins won't be visible
Candling is a method used to check if an egg is fertile and developing properly. It involves examining the contents of an egg by placing it in front of a bright light in a darkened room. Typically, a candler will look for a dark spot (the embryo) and visible red veins.
While movement is one indicator of a developing embryo, it is not always necessary to see movement to determine that an egg is fertile. Veins may be visible as early as day 3, and by day 6 or 7, the embryo should be visible in the middle of the egg with spider-like veins stretching out into the yolk. By day 8, the embryo will be large enough that you can see it wiggling and kicking in the egg.
However, as the embryo develops and fills up more of the egg, there is less space to move, and it becomes less active. Therefore, it is normal to see less movement during later stages of development. Additionally, it can be challenging to see the embryo and its movement, as it may be in the centre or on the opposite side of the egg from where you are viewing.
In some cases, eggs may not show any movement at all, even during early stages of development. This does not necessarily indicate that the egg is infertile, as some users have reported seeing veins and other signs of development without ever observing movement. Therefore, it is important to look for other indicators of fertility and development, such as the presence of veins, a dark spot, and the growth of blood vessels.
In summary, while movement can be one indicator of a developing embryo, lack of movement does not always mean that veins will not be visible. It is essential to consider other factors and continue to monitor the egg's development over time to make an accurate assessment.

Brown or green eggs make vein visibility more difficult
When candling eggs, the colour of the shell can impact how well you can see the veins. Dark-shelled eggs, such as brown or green eggs, are much harder to see through. This is because the darker colour of the shell makes it more difficult to get a good view of the inside. Therefore, it is recommended to candle brown or green eggs earlier on in the incubation timeline, around day 5 or 6. By this time, veins may be visible, and you will be able to determine whether the egg is fertile.
On day 7, veins are typically visible in fertile eggs, appearing like spider-like veins stretching out into the yolk. However, with brown or green eggs, it may be necessary to candle in a dark room and use the brightest light source available to get a better view. Even then, it can be challenging to see the embryo and veins clearly, and you may need to wait another day or two before trying again.
As the embryo develops, it becomes even harder to see inside brown or green eggs. By day 14, the egg is getting full, and it is normal to find it challenging to see the veins and embryo. To get a better view, you can try candling from different angles and in different locations. However, it is important to minimise handling the eggs and return them to the incubator as soon as possible to preserve heat and humidity levels.
In summary, brown or green eggs do make vein visibility more difficult when candling. To optimise vein visibility, candle earlier in the incubation process, use a bright light source, candle in a dark room, and try viewing from different angles. Remember to handle the eggs gently and minimise disruptions to the incubator to give the embryos the best chance of successful development.

Frequently asked questions
It is suggested that you candle quail eggs at 6 days, as 4 days is too early. You should be able to see veins by day 7.
You may be able to see veins by day 3. By day 7, spider-like veins will be stretching out into the yolk.
If you don't see veins by day 7, it could be a "quitter". This is when the contents are cloudy and moving around. You can leave the egg until day 14, when it will be easier to identify.
This could be because the shell is very dark. As long as you can see some veining, you can assume things are progressing well.
If there are no veins, the egg is infertile. It will look clear with no dark spots or blood vessels.
