Before the chicken hatches, it's often necessary to store a large number of eggs for an extended period. If not handled properly, the eggs can spoil or develop issues that negatively impact the incubation process. To ensure the best results, several key factors should be carefully considered when storing eggs:
First, maintaining the right temperature is crucial. Eggs stored at temperatures above 24°C may start developing prematurely, leading to aging embryos and higher rates of stillbirths. On the other hand, if the temperature drops below 5°C, the eggs may freeze and lose their ability to hatch. The ideal storage temperature is between 10°C and 15°C, which helps maintain the viability of the embryos.
Second, humidity control is equally important. The eggshell has tiny pores through which moisture can escape during storage. To prevent excessive drying, the storage area should maintain a relative humidity of 70% to 80%. However, if the humidity is too high, mold can grow, which can damage the eggs and reduce hatchability.
Third, regular egg turning is essential. If the eggs are left in one position for too long, the yolk and blastoderm may stick to the shell, causing early embryonic death. It’s recommended to place the blunt end of the egg upward so that the yolk stays centered. For longer storage periods, turning the eggs once a day helps prevent adhesion and ensures a healthy hatch rate.
Fourth, the storage environment should be clean and well-ventilated. The egg storage room, trays, and racks must be kept clean to avoid contamination. Avoid using airtight containers, as they can trap moisture and promote bacterial growth. Proper airflow is vital for maintaining good egg quality.
Lastly, never wash or scrub the eggs. After being laid, eggs have a natural protective layer called the cuticle, which covers the pores on the shell. This layer prevents water loss and blocks bacteria from entering the egg. Washing the eggs removes this protective coating, increasing the risk of spoilage and reducing overall egg quality.
By following these guidelines, you can significantly improve the chances of successful hatching and maintain the health of your eggs throughout the storage period.
