Candling goose eggs is a process that involves passing eggs under a bright electric light to view their contents. It is typically done around day 10 of the 28-35 day incubation period to check for fertility and remove infertile or rotten eggs. During candling, farmers look for signs of growth, such as veins and movement, to determine if the eggs are developing properly. Additionally, candling can be used before incubation to inspect for cracks that may allow bacteria to enter and cause infection. Proper incubation practices, such as maintaining high humidity and turning eggs daily, are crucial for successful hatching, and candling plays a vital role in ensuring the health and viability of goose eggs.

What You'll Learn
Goose eggs should be candled around day 10
Candling goose eggs is a straightforward process that involves passing the eggs under a bright electric light to view their contents. It is typically done around day 10 of the 28-35 day incubation period to check fertility and identify viable eggs. By day 10, you should be able to observe veins and perhaps some movement inside the eggs.
Candling is essential to ensure the removal of non-viable or infertile eggs, which can rot and potentially explode, contaminating the fertile eggs and the incubator. Before incubation, candling can also help identify cracks in the eggs, which may allow bacteria to enter and cause premature embryo death.
To get the best hatching results, it is recommended to set the eggs horizontally and turn them over completely at least four times a day. Maintaining the right humidity is crucial, and goose eggs require high humidity. Sprinkling or dipping the eggs with lukewarm water once daily after the first 15 days is recommended.
Additionally, the temperature in the hatching compartment should be maintained at 37°C with 80% relative humidity during the peak of hatching. After the peak, the temperature can be reduced to 36.5°C with 70% humidity. It is also essential to clean and sanitise the incubator trays and incubators when they are not in use to prevent any contamination.

Candling involves passing eggs under a bright light to view their contents
Candling is a process used to assess the fertility and development of eggs, especially during the incubation period. It involves passing a bright light behind the egg to observe its internal contents, revealing details about its viability. This technique is called candling because the original sources of light used were candles. However, modern alternatives like electric lights are now often used instead, as they are less of a fire hazard.
During candling, a bright and focused beam of light is directed through the eggshell to inspect the egg's contents. This allows observers to identify signs of fertility, defects, or freshness. For instance, the size of the air cell at the wide end of the egg indicates freshness, as it shrinks with age. Additionally, the shadow cast on the shell by the yolk reveals the egg's age; older eggs have thinner albumin, resulting in a sharper shadow as the yolk rests closer to the shell.
Candling can be performed at various stages of incubation, such as around days 5-6, 9-10, and sometimes closer to the day of transfer to the hatcher. Conducting candling on day 9 or 10 can improve accuracy and minimise errors. This timing also allows for the use of a ""candling table," where an entire tray of eggs is illuminated from below, increasing efficiency. However, this method may compromise accuracy, especially with a high number of 'clears' or non-viable eggs.
To ensure accuracy and efficiency, it is recommended to avoid candling between days 11 and 14 of incubation as it can disrupt embryo movement. When candling on day 9 or 10, it is important to fill empty spaces on the setter tray by shifting remaining eggs to create complete rows, leaving the front rows empty. Removing clear eggs is suggested if they exceed 10-15% of the total.
Candling is an essential practice in embryology and the egg industry. It helps improve chick quality by identifying potential issues and removing non-viable eggs, resulting in higher hatch rates and healthier chicks. Additionally, data collected from candling can be used to evaluate hatchery performance and make necessary adjustments to optimise results.

It helps identify cracked eggs, which may become infected
Candling goose eggs involves shining a bright light into them, allowing you to see their contents and check whether they are developing properly. It is a useful way to identify cracked eggs, which may become infected.
Candling gets its name from the days before electric light bulbs, when people used candles to try to see through the egg in a darkened room. Now, people use mains-powered or battery-operated egg candlers, or even just flashlights.
When candling, you can identify cracked eggs that are not visible to the naked eye. Cracked eggs are more susceptible to harmful bacteria, which can affect the development of the embryo. If you find a cracked egg, it is recommended that you do not discard it right away. Instead, make a note of the crack and check the egg's progress later.
During incubation, candling an egg allows you to see the developing embryo inside the shell and remove non-viable eggs. Commercially, this enables egg packers to remove eggs with hairline cracks, blood spots, or other undesirable contents.
It is important to identify and remove non-viable eggs during the incubation process. Otherwise, they can begin to rot and eventually burst inside the incubator, contaminating the other eggs with bacteria and creating a foul odour.

Candling can also identify fertile eggs
Candling is a process that involves illuminating the interior of an egg to see what is inside the shell. It is a useful way to identify fertile eggs and remove non-viable ones. By candling, one can observe the growth of an embryo and determine whether an egg is fertile or infertile. Typically, candling is done after a week of incubation by placing the egg on an egg candler in a dark room.
During candling, one should look for a dark dot, the embryo, and the spider-like blood veins spreading out around the egg. The embryo may be easier to spot if it is up against the side of the shell, and sometimes, one may even see movement or the heart beating. If the egg is fertile, one will see the embryo as a dark spot with spider-like veins stretching out from it.
It is important to note that it can be challenging to see the embryo initially, and it may be necessary to rotate the egg to find the best viewing angle. Additionally, it is recommended to wait a day or two before trying again if the embryo is still not visible. In some cases, a thin ring around the inside of the egg indicates early embryonic death, where the embryo died within a few hours of the start of incubation.
Candling can also be performed before placing the eggs in an incubator, although it may be difficult to differentiate between good and bad eggs at this stage. However, it provides a baseline for comparison later on in the incubation process.

Eggs should be weighed and checked for appropriate humidity during candling
Candling goose eggs is typically done around day 10 of their 28-day incubation period. During this process, it is important to weigh the eggs and check for appropriate humidity. Weighing the eggs is crucial as it helps identify any weight loss during incubation, which can be a sign of embryo death. This weight loss can be caused by incorrect humidity levels, so regular monitoring of humidity is essential to ensure the eggs' viability.
Embryo deaths can occur due to various factors such as rough handling, incorrect storage, adverse genetic traits, or ageing of the breeder flock. While some of these factors may be unavoidable, others can be easily corrected. By regularly weighing the eggs and monitoring the humidity, you can identify any issues early on and take corrective actions to prevent embryo deaths.
To ensure the right humidity, it is recommended to monitor the air sac size in the eggs. The porosity of eggs varies with size, age, and season, all of which can impact the required humidity levels. By weighing the eggs and monitoring the air sac size, you can adjust the humidity in your incubator to create the optimal environment for the embryos' development.
Additionally, candling at specific intervals can help identify any issues with the eggs. During candling, you can observe the veins and movement within the eggs, which indicate the growth and viability of the embryo. By combining regular candling with weight checks and humidity monitoring, you can increase the chances of successful incubation and hatching.
Overall, weighing the eggs and checking for appropriate humidity during candling are crucial steps in the process of incubating and hatching goose eggs. By following these steps and making any necessary adjustments, you can create the optimal environment for the embryos' development and increase the likelihood of successful hatching.
