how to store fertile eggs before incubation

Storing fertile eggs properly before incubation is crucial for hatching success. Improper storage can significantly reduce hatchability or even render the eggs infertile. This guide outlines best practices for maintaining egg quality and maximizing your chances of healthy chicks.

Factors Affecting Fertile Egg Storage

Several factors influence how well fertile eggs store before incubation:

Egg Temperature:

Maintaining a consistent temperature is paramount. Ideal storage temperatures range from 50-60°F (10-15°C). Temperatures above 60°F can accelerate embryonic development, potentially leading to early death. Conversely, temperatures below 50°F can damage the embryo.

Humidity:

Humidity levels should be around 75-80%. This prevents excessive moisture loss, which can lead to shrinking or cracking. Low humidity increases the risk of dehydration, while high humidity fosters the growth of mold and bacteria.

Egg Position:

Always store fertile eggs with the large end up. This helps keep the yolk centered, preventing it from sticking to the shell membrane and damaging the developing embryo. Turning the eggs regularly (at least once a day) is also beneficial. This prevents the yolk from sticking to the shell and improves hatchability.

Duration:

The longer fertile eggs are stored, the lower the hatchability rate. Ideally, eggs should be incubated as soon as possible after collection. However, a storage period of 7-10 days is generally acceptable if conditions are optimal. Beyond 10 days, hatchability decreases significantly.

Step-by-Step Guide to Storing Fertile Eggs

Gather Supplies: You'll need a cool, dark place to store your eggs, such as a refrigerator. A dedicated egg storage container is highly recommended. You could use a carton designed for egg storage or an egg incubator that allows for temperature and humidity control.
Clean Eggs Gently: If necessary, gently wipe eggs clean with a soft cloth. Avoid washing them as this can remove the natural protective cuticle.
Store Eggs with Large End Up: Place the eggs in their storage container with the larger end pointing upward.
Maintain Temperature and Humidity: Store eggs in a cool, dark place as described above. Use a thermometer and hygrometer to monitor the temperature and humidity levels. This is especially crucial for longer storage periods.
Turn Eggs Regularly: Turn the eggs gently at least once a day, rotating 90 degrees.
Monitor for Cracks or Damage: Regularly check your eggs for any cracks or damage. Discard any damaged eggs immediately to prevent contamination.

What Not To Do When Storing Fertile Eggs

Don't wash eggs before storage: Washing removes the natural protective coating, increasing the risk of bacterial contamination.
Don't store eggs at room temperature: Room temperatures are too warm and inconsistent for proper storage.
Don't leave eggs un-turned: Unturned eggs lead to yolk adhesion and compromised embryonic development.
Don't store eggs for extended periods: While some storage is fine, the longer you store them the lower your hatch rate will likely be.

Troubleshooting: Low Hatch Rates Despite Proper Storage

Even with careful storage, several factors can still influence hatch rates. These include:

Egg quality: The fertility and overall health of the eggs from the parent birds will impact the success of incubation.
Incubation conditions: Incorrect incubation temperature and humidity after storage can also affect hatching success.
Breed of poultry: Some breeds may have naturally lower fertility or hatchability rates.

Conclusion:

Proper storage of fertile eggs before incubation is a critical step for successful hatching. By following these guidelines, you can maximize your chances of obtaining healthy chicks. Remember to prioritize temperature, humidity, egg positioning, and duration to ensure the eggs remain viable and ready for incubation. Consistent monitoring and attention to detail are key to success!
