What does the temperature in centigrade have to be hatch chicken eggs?

The ideal temperature for hatching chicken eggs is 37.5°C (99.5°F).

Here's why:

* Consistency is Key: Maintaining a consistent temperature within a narrow range is crucial for healthy embryonic development.

* Fluctuations: Even small fluctuations (more than 1°C) can lead to developmental issues, lower hatch rates, or deformed chicks.

* Temperature Monitoring: Use a reliable incubator thermometer to accurately track the temperature and make adjustments as needed.

Important Considerations:

* Humidity: Along with temperature, maintaining appropriate humidity (around 50-60%) is also essential for successful hatching.

* Turning: Regular turning of the eggs (every few hours) is necessary to ensure proper development and prevent the embryo from sticking to the shell.

* Incubation Time: The incubation period for chicken eggs is typically around 21 days.

Remember: Hatching chicken eggs is a delicate process, and achieving success requires careful attention to temperature, humidity, and other factors.
