Humidity and Temperature for Hatching Quail Eggs
Incubating quail eggs is an exciting part of raising quail, offering the opportunity to grow your flock and witness the miraculous process of life. However, successful incubation requires careful attention to both humidity and temperature. These factors play a critical role in embryo development, hatching success rates, and the overall health of your chicks.
In this post, I’ll be sharing why humidity and temperature matter, the ideal settings for quail eggs, and how to maintain a stable incubation environment.
Why Humidity and Temperature Are Critical
Humidity and temperature work together to create the conditions needed for embryos to grow and hatch. If either factor is too high or too low, it can disrupt the development process and lead to problems like weak chicks or failed hatches. Understanding their importance helps you manage your incubator effectively and achieve better results.
Temperature
Quail embryos develop best within a very narrow temperature range. If the temperature is too low, the embryos may develop slowly or fail to hatch. If it’s too high, they may overheat, which can lead to deformities or death. A consistent temperature is essential for uniform development across all the eggs.
Humidity
Humidity controls how much moisture the eggs lose during incubation. Eggs naturally lose water through the pores in their shells, and this moisture loss is critical for proper air cell formation. If the humidity is too high, the air cell will be too small, and the chick may drown during hatching. If it’s too low, the air cell will be too large, and the chick may stick to the shell, making it difficult to hatch.
Ideal Temperature and Humidity for Quail Egg Incubation
For Coturnix quail eggs, the following settings work best:
- Temperature: 99.5°F (37.5°C) in a forced-air incubator or 101°F (38.3°C) in a still-air incubator.
- Humidity During Incubation: Maintain 45–50% relative humidity for the first 14 days.
- Humidity During Hatching: Increase humidity to 65–70% for the final 3 days before hatching.
These settings mimic the natural conditions a broody quail would provide, ensuring the embryos have the right environment to thrive. For a step-by-step guide to the entire incubation process, check out our post on How to Hatch Coturnix Quail Eggs: Incubation Tips for Beginners.
How to Monitor and Control Humidity and Temperature
Proper monitoring and control are crucial for success. Here’s how to maintain the ideal conditions:
Use a Reliable Thermometer and Hygrometer
Invest in high-quality, accurate tools to measure temperature and humidity inside the incubator. Place them at egg level for the most accurate readings. Avoid relying solely on built-in incubator displays, as they can sometimes be inaccurate. A faulty thermometer and/or hygrometer are the number one culprit in failed or disappointing hatches.

Calibrate Your Incubator
Before starting a new batch of eggs, test your incubator to ensure it holds steady temperature and humidity levels. Make adjustments as needed and allow the incubator to run for 24 hours to stabilize. This initial setup period helps identify any potential issues with the equipment before you place your eggs, giving you time to correct problems and avoid risking the hatch.
Control Humidity with Water Reservoirs
Most incubators have built-in water reservoirs. Fill them to the recommended levels based on your desired humidity. To increase humidity, add sponges or small containers of water. To decrease it, remove water or reduce the surface area exposed to air.
Adjust Temperature Carefully
If the incubator’s temperature fluctuates, adjust it in small increments and allow time for it to stabilize. Rapid changes can stress the embryos, leading to developmental issues or even failed hatches. Consistency is key, so monitor the incubator closely and double-check its placement in a room with stable ambient temperature to avoid unnecessary fluctuations.
Avoid Opening the Incubator Frequently
Every time you open the incubator, the temperature and humidity drop, which can stress developing embryos. Minimize openings to candle eggs or refill water reservoirs. If you must open the incubator, work quickly and efficiently to limit exposure time. Consider grouping tasks, like adding water or turning eggs, to reduce the frequency of openings and maintain a stable environment.
Common Problems with Humidity and Temperature
Even with careful monitoring, issues can arise. Here are some common problems and how to address them:
- Hot Spots in the Incubator: Rotate the eggs periodically to ensure even heat distribution.
- Humidity Drops: Add water immediately to the reservoirs and consider using a humidifier in the room to stabilize conditions.
- Overheating: Turn down the temperature and allow the incubator to stabilize. If you can’t regulate it, consider upgrading to a more reliable model.
Why Candling Is Optional
Candling quail eggs is a popular method for monitoring embryo development, but it’s not strictly necessary for a successful hatch. By shining a light through the egg, candling allows you to check for proper air cell growth, embryo movement, and fertility. For those who want to actively track progress, candling around day 7 and day 14 can provide useful insights.
However, many homesteaders, including us at Forget-Me-Not Quail Farm, choose not to candle quail eggs. With proper humidity and temperature management, the embryos will develop just fine without interference. Skipping candling can reduce handling stress on the eggs and minimize the risk of accidents. Whether you decide to candle or not, maintaining the right incubation conditions remains the most important factor for a successful hatch.
Frequently Asked Questions
No, accurate monitoring tools are essential for maintaining the proper environment inside the incubator.
Low humidity can cause excessive moisture loss, leading to large air cells and chicks becoming stuck to the shell during hatching.
Yes, extreme room temperatures can impact the incubator’s ability to maintain consistent conditions. Keep the incubator in a stable, draft-free room.
Yes, even under ideal conditions, not all eggs will hatch. Infertility or developmental issues can naturally occur.
Final Thoughts
Maintaining the proper humidity and temperature is the cornerstone of successful quail egg incubation. With careful monitoring, the right tools, and a stable environment, you can significantly improve your hatch rates and welcome healthy, robust chicks into your flock. As you refine your incubation skills, remember that preparation is key to preventing common issues and achieving consistent results.
After your chicks hatch, ensuring a smooth transition to the brooder is just as important as incubation.
