Hatching chicken eggs is an exciting and rewarding process, whether you're a backyard poultry keeper or a small homesteader. But if you want healthy, fluffy chicks at the end of your 21-day journey, you need to get one thing right: the chicken incubation temperature. This article will walk you through the science of incubation, the ideal temperature and humidity levels, and how to monitor them with precision using the ThermoPro TP357 Digital Hygrometer Thermometer.
Whether you have a DIY incubator or a commercial unit, the TP357 lets you confidently manage the best temp for incubating chicken eggs, even from another room.
Setting Up Your Incubator for Optimal Conditions
Follow these steps for best results:
- Place your incubator in a draft-free room away from direct sunlight.
- Pre-warm your incubator 24 hours before adding eggs.
- Use two hygrometer thermometers to verify accuracy.
- Place sensors at egg level inside the incubator.
- Adjust water trays or sponges to control humidity.
Avoid opening the lid too often, especially during lockdown (days 19–21). Too much fluctuation in the chicken egg incubation temperature at this stage can prevent hatching.
What to Do if Temperatures Fluctuate
If the power goes out or your incubator malfunctions, don’t panic. Here are a few emergency tips:
- Insulate the incubator with blankets
- Use warm rice socks or hot water bottles as a temporary heat source
- Keep monitoring using the ThermoPro TP357 to avoid overheating
Brief drops of 1–2°F for under an hour are usually survivable, but anything more could affect your hatch rate. Quick intervention is key.

Troubleshooting: If Your Eggs Don’t Hatch
Even experienced hatchers lose some embryos. Here are possible causes:
- Too low or too high chicken incubator temperature
- Incorrect humidity levels
- Fertility issues with the eggs
- Turning eggs too infrequently
If you have multiple chickens in incubator but only a few hatch, candle the eggs after day 7 to check development. After day 21, open unhatched eggs to examine embryo development. Keep notes to improve for the next hatch.
After Hatching: Maintaining Brooder Temperature
Your job doesn’t stop once the chicks hatch. For the first week, keep the brooder temperature around 95°F, reducing it by 5°F each week. Again, your TP357 will come in handy to avoid overheating or chilling.
Happy chicks = healthy flock.
Conclusion: Master the Art of Incubation
Getting the best temp to hatch chicken eggs is not about guesswork—it’s science. With the right knowledge, tools, and a reliable digital monitor like the ThermoPro TP357, you can turn fertilised eggs into healthy chicks with confidence.
So if you’re planning your next hatch, invest in precision. Because when it comes to chicken incubation temp, every degree matters.
