Proper humidity levels are crucial for maintaining the viability of fertile eggs during storage. Here are the key humidity requirements to consider when storing fertile eggs:

Relative Humidity: Fertile eggs should be stored in an environment with a relative humidity level between 75% and 80%. This range helps prevent excessive moisture loss from the eggs, which can lead to dehydration and decrease hatchability. Maintaining the correct humidity level is essential for preserving the eggs’ quality and the health of the developing embryos.

Monitoring Humidity: Regularly monitor the humidity levels in the storage area using a hygrometer. Place the hygrometer near the eggs to get an accurate reading of the relative humidity. Make adjustments as needed to maintain the desired humidity range. It is important to note that different breeds may have slightly different humidity requirements, so be aware of any specific recommendations for the type of poultry you are working with.

Adding Moisture: If the humidity level in the storage area falls below the desired range, you can add moisture to increase it. One simple method is to place a shallow tray or container filled with water inside the storage area. As the water evaporates, it will help raise the humidity level. Additionally, you can use a humidifier or misting device to introduce moisture into the air. Be cautious not to oversaturate the environment, as excessively high humidity levels can lead to fungal growth and negatively affect embryo development.

Avoiding Condensation: While maintaining proper humidity is important, it is equally crucial to prevent condensation from forming on the eggs’ shells. Excessive condensation can create a breeding ground for bacteria and increase the risk of contamination. To avoid condensation, ensure proper ventilation in the storage area, allowing for adequate air circulation. If condensation does form on the shells, gently blot it away with a paper towel to prevent it from negatively impacting the eggs.

Record-keeping: Keep a record of the humidity levels in the storage area, including daily measurements and any adjustments made. This record will help you track the humidity conditions over time and identify any trends or issues that may arise. It can also be a valuable resource for future storage batches, allowing you to fine-tune your humidity management techniques.

By maintaining the proper humidity levels during the storage of fertile eggs, you can ensure the optimal conditions for embryo development and maximize hatch rates. Regular monitoring, appropriate moisture management, and careful record-keeping are essential in creating a favorable environment for the eggs, ultimately leading to the successful hatching of healthy chicks.

Egg Turning During Storage

Egg turning plays a crucial role in maintaining the viability and improving the hatchability of fertile eggs during storage. While turning is typically associated with incubation, it can also be beneficial during the storage period. Here are the key aspects to consider regarding egg turning during storage:

Importance of Egg Turning: Turning the eggs during storage helps prevent the embryo from sticking to the inner shell membrane and allows for even distribution of nutrients and gases inside the egg. This mimics the natural movement the eggs would experience when incubated by a broody hen.

Frequency of Turning: During storage, it is recommended to turn the eggs at least once or twice a day. This can be done by gently rolling or tilting the eggs, ensuring that each egg is rotated 180 degrees. This frequency of turning helps maintain the proper orientation of the embryo, prevents adhesion, and improves overall embryo development.

Turning Method: When turning the eggs, it is important to handle them with care to avoid damaging the delicate embryos. Use your hands or a gentle rolling motion to rotate the eggs. Avoid shaking or jostling them, as this can lead to excessive movement, potential damage, or disruption of the embryo’s positioning.

Positioning and Marking: To keep track of the turning process, you can mark one side of the eggs with an “X” and the other side with an “O.” This helps ensure that you are turning the eggs consistently and in the correct direction. You can also use an egg turning tray or carton specifically designed for storage to simplify the process.

Incubation-Like Environment: To provide an incubation-like environment during storage, consider using an egg turning device specifically designed for storage. These devices gently rock or tilt the eggs at regular intervals, mimicking the movement experienced during incubation. They maintain a consistent turning schedule even when you are unable to manually turn the eggs throughout the day.

Transitioning to Incubation: When you are ready to transfer the eggs from storage to the incubator, ensure that they are properly positioned and oriented for consistent turning during incubation. This helps maintain the embryos’ health and provides optimal conditions for successful hatching.

By incorporating regular egg turning during the storage period, you can enhance the viability and hatchability of fertile eggs. Proper egg turning mimics the natural incubation process, preventing adhesion and maintaining embryo health. Whether you choose to manually turn the eggs or use an automated turning device, consistent turning will contribute to improved hatch rates and the development of healthy chicks.

Checking Egg Fertility Before Incubation

Before placing eggs into the incubator, it is important to determine their fertility. Checking the fertility of eggs helps ensure that only viable eggs are included in the incubation process, increasing the chances of successful hatching. Here are the key methods for checking egg fertility before incubation:

Candling: Candling is a commonly used method to assess egg fertility. It involves shining a bright light source through the egg to reveal the embryo’s development. Fertile eggs typically show clear signs of development, such as the presence of veins, darkening of the egg mass, or movement. Infertile eggs, on the other hand, appear clear or have a cloudy appearance with no discernible signs of growth.

Incubation Test: The incubation test involves placing a small number of eggs in a separate incubator or a warm, controlled environment to determine their fertility. Monitor these eggs closely over a few days to observe any signs of development, such as pip marks, hatching, or embryo movement. This method provides a more accurate assessment as it allows for the eggs to undergo partial incubation and gives a better indication of their fertility status.

Air Cell Inspection: Eggs with a developed air cell are more likely to be fertile. Inspect the air cells at the blunt end of the egg by holding the egg up to a strong light source. Fertile eggs usually have a prominent air cell, while infertile eggs may have smaller or underdeveloped air cells.

Blood Spot Examination: Blood spots or small, red specks found on the egg yolk can indicate fertility. While not all blood spots are a clear indication of embryo development, they can provide some insight into the overall fertility of the eggs. However, it is important to note that blood spots can also occur in infertile eggs due to other factors, such as minor blood vessel ruptures during egg formation.

Cracking Open: In some cases, if there is doubt about the fertility of an egg, cracking it open can provide a definitive answer. A fertilized egg will show signs of embryo development, including the presence of a distinct embryo, blood vessels, or a partially formed chick. However, this method should be used as a last resort, as it renders the egg unusable for incubation.

Record-keeping: Maintain detailed records of the fertility assessments, including the date, the number of eggs assessed, and the results. This information is valuable for future reference and helps track the fertility rates of your breeding stock over time.

By checking egg fertility before incubation, you can ensure that only viable eggs are being incubated, saving time, effort, and resources. Whether you use candling, the incubation test, air cell inspection, blood spot examination, or a combination of methods, regular fertility checks will improve the chances of successful hatching and increase the overall productivity of your breeding program.
