Artificial incubation is one of the most exciting aspects of raising quails, but it is also one of the most demanding. A high-quality incubator that is correctly adjusted and properly used can make the difference between poor hatch rates and outstanding results.
Many breeders focus all their attention on fertile eggs while overlooking one essential factor: the accuracy of the incubator. Temperature, humidity, ventilation and sensor calibration all play a crucial role in embryo development.
In this guide, you'll learn how to choose the right incubator, why calibration is essential and which best practices will help you achieve the highest possible hatch rates.
Not All Incubators Are Created Equal
Today, incubators are available in every price range, from inexpensive beginner models to professional equipment.
However, price alone does not determine quality. The most important feature is the ability to maintain stable incubation conditions throughout the entire incubation period.
A good incubator should provide:
- Stable temperature;
- Consistent humidity;
- Uniform air circulation;
- Reliable automatic egg turning (if equipped).
These four elements are the foundation of successful incubation.
Temperature: The Most Important Factor
For most forced-air incubators used with Japanese quail eggs, the recommended temperature ranges between 37.5°C and 37.7°C. Always follow the manufacturer's recommendations for your specific model.
Although it may seem insignificant, a continuous difference of only 0.3°C to 0.5°C can result in:
- Lower hatch rates;
- Slower embryo development;
- Weaker chicks;
- Increased mortality before hatching.
For this reason, you should never rely solely on the temperature displayed by the incubator.
Why Should You Calibrate an Incubator?
One of the most common issues with entry-level incubators is that the displayed temperature is not always the actual temperature inside the machine.
It is not unusual for an incubator to display 37.5°C while the real temperature is 36.9°C or even 38.0°C.
Although the difference appears small, it can significantly reduce hatch success.
For this reason, one of the best investments is often not a new incubator, but a high-quality digital precision thermometer.
Comparing the actual temperature with the incubator's display allows you to calibrate the machine and improve its accuracy.
Humidity Is Just as Important
Throughout most of the incubation period, eggs must lose a small amount of moisture at a controlled rate.
During the final days before hatching, humidity should be increased to prevent the membranes from drying out and to help chicks hatch more easily.
Incorrect humidity levels may cause:
- Chicks sticking to the membranes;
- Delayed hatching;
- Difficulty breaking the shell;
- High mortality during hatch.
Built-in Hygrometers Are Not Always Accurate
Just like temperature sensors, built-in humidity sensors may also display inaccurate readings.
For this reason, many experienced breeders use an independent digital hygrometer, placing it at egg level inside the incubator.
A simple verification can greatly improve incubation results.
Air Circulation Matters
Good airflow helps maintain a uniform temperature throughout the incubator.
Forced-air incubators generally provide better results than still-air models, particularly when incubating larger numbers of eggs.
Proper ventilation also ensures a continuous supply of oxygen, which is essential for embryo development.
Automatic Egg Turning
Eggs should be turned several times each day to prevent the embryo from sticking to the shell membrane.
Automatic turning systems provide several advantages:
- Greater consistency;
- Less handling;
- Reduced risk of forgetting to turn the eggs.
Automatic turning should be stopped approximately three days before hatching, allowing the chicks to position themselves correctly for emergence.
Cleaning Your Incubator
After every incubation cycle, the incubator should be thoroughly cleaned.
Broken shells, dust and organic residue can encourage bacteria and mould growth, potentially affecting future hatchings.
Regular cleaning also extends the lifespan of the incubator.
Is a More Expensive Incubator Always Better?
Not necessarily.
Many affordable incubators deliver excellent results when properly calibrated and correctly operated.
Likewise, even a premium incubator can produce disappointing hatch rates if temperature or humidity are inaccurate.
The real keys to successful incubation are:
- Stable temperature;
- Accurate measurements;
- Proper calibration;
- High-quality fertile eggs;
- Correct incubation management.
The Most Common Mistakes
Beginners often make the same mistakes:
- Trusting only the incubator display;
- Opening the incubator too frequently;
- Never checking the actual humidity;
- Failing to verify temperature accuracy;
- Placing the incubator in direct sunlight or in rooms with significant temperature fluctuations.
Conclusion
An incubator is an outstanding tool—but only if its readings are accurate.
Verifying temperature and humidity using independent measuring devices is one of the best habits any breeder can develop. Often, just a few tenths of a degree or a few percentage points of humidity make the difference between average and exceptional hatch rates.
At Ovolis, we always recommend running a new incubator for 24 to 48 hours before placing fertile eggs inside. This allows you to verify its stability and correct any inaccuracies before incubation begins.
Successful incubation is not a matter of luck. It is the result of precision, consistency and patience. Paying attention to these details will reward you with healthier chicks and significantly higher hatch rates.
