Hatching chickens at home is a rewarding experience, but it's important to get the temperature and humidity right. Incorrect temperature and humidity levels can interfere with the growth and development of the embryo and stop it from developing further. The temperature in your incubator should be maintained between 37 and 39 degrees Celsius or 99.5 degrees Fahrenheit. The humidity levels should be between 50 and 55% and then increase to about 60 to 65% for the final three days of incubation.
| Characteristics | Values |
|---|---|
| Temperature | Between 37 and 39 degrees Celsius or 99.5 degrees Fahrenheit |
| Humidity | Between 50 and 55% for the first 18 days, increasing to about 65% for the final three days |
| Ventilation | Increase as embryos grow bigger, especially from days 18-21 |
| Egg turning | Critical to chick development and to prevent the chick from sticking to the shell |
| Brooder temperature | 95 degrees Fahrenheit for the first week, reducing by 5 degrees each week until chicks are accustomed to room temperature |

What You'll Learn
The ideal temperature range is 37-39°C
The ideal temperature range for an incubator with day-old chicks is 37-39°C. This temperature is critical for the successful hatching of eggs. Incorrect temperatures can cause the embryo to stop developing, resulting in dead embryos.
To ensure the temperature stays within this range, it is important to have a good-quality incubator with accurate temperature control. The incubator should also have an alarm to alert you when the temperature is out of range. In addition, a thermometer can be used to monitor the temperature regularly.
It is also important to maintain the correct humidity levels in the incubator, as this determines how much moisture an egg loses during incubation. The humidity should be between 50 and 55% and then increased to about 60-65% for the final three days of incubation. Incorrect humidity can lead to "shrink-wrapped" chicks or drowning in the shell.
Preparing the incubator in advance and placing it in an area with steady ambient temperatures can help maintain the ideal temperature. Additionally, only opening the incubator when necessary can prevent heat from escaping.
By following these guidelines and maintaining the ideal temperature range of 37-39°C, you can increase the chances of successful hatching and ensure the healthy development of your day-old chicks.

Humidity is critical to hatching success
The temperature in an incubator for day-old chicks should be maintained between 37 and 39 degrees Celsius. It is important not to overheat the incubator as this can reduce the chance of hatchability and result in abnormal chicks.
Humidity is critical to the success of hatching chicks. During incubation, all avian eggs lose water through the pores in the eggshell. The rate of water loss is determined by factors such as eggshell temperature and air humidity. The higher the humidity level, the lower the rate of water loss.
The correct humidity level ensures a healthy air cell size for the embryo to inflate its lungs after internal pipping. If the humidity is too high, the air cell can be too small, and the embryo's lungs may not fully inflate, leading to an increased number of embryos pipping but not hatching. Conversely, too much water loss due to low humidity can cause embryo dehydration.
Regulating humidity during incubation is crucial to achieving optimal hatchability and chick quality. During the first 18 days, the relative humidity should be around 60 percent, increasing to 65-70 percent during the last three days of the hatching period.
Modern incubators make it easier to maintain consistent temperature and humidity levels. However, it is important to monitor these levels regularly and make adjustments as needed to ensure the best possible hatching success.

The brooder temperature should be 95°F for the first week
The brooder temperature should be maintained at 95°F for the first week. This is vital to ensure the chicks' survival and development. After the first week, the temperature can be reduced by about five degrees each week until the chicks adjust to room temperature or grow enough feathers to keep themselves warm.
Maintaining the correct temperature is crucial for the successful hatching of chicks. The temperature range in the incubator should be between 37°C and 39°C. Keeping the temperature constant is essential, as fluctuations can interfere with the embryo's growth and development, reducing the chances of hatching.
The humidity levels in the incubator are also critical for hatching. The ideal humidity is between 50% and 55% for most of the incubation period, increasing to about 60% to 65% in the final three days. Humidity affects the amount of moisture lost by the eggs during incubation, which is necessary for the chicks to hatch successfully.
Additionally, the number of eggs placed in the incubator matters. It is recommended to set a minimum of six eggs at a time, as chickens are flock animals and having companions is essential for their well-being.
Overall, providing the right environment in the incubator and brooder is key to ensuring the healthy development and survival of chicks.

Incorrect humidity can cause shrink-wrapping
The temperature in your incubator should be maintained between 37 and 39 degrees Celsius or 100.5 degrees Fahrenheit. The humidity levels should be between 40% and 55% during the first 18 days of incubation and then increased to about 60-75% for the final three days.
Now, incorrect humidity can cause shrink-wrapping. Shrink-wrapping is a condition where the chick gets trapped inside the egg. It occurs when the membrane dries out and becomes tough, contracting tightly around the chick's body. This prevents the chick from moving and breaking free of the shell.
During the last 2-3 days of incubation, known as the "lockdown" period, it is critical to raise the humidity to at least 60% RH to keep the inner membrane soft. If the humidity is too low during this period, the eggs can lose too much moisture, leading to shrink-wrapping.
On the other hand, if the humidity is too high, the eggs can absorb excess moisture, resulting in swollen eggs. This can cause deformities and increase the risk of drowning for the chicks. Therefore, maintaining the recommended humidity range is crucial for successful hatching and to prevent shrink-wrapping.
To manage humidity levels effectively, it is essential to have a good-quality incubator with accurate monitoring and control features. Regularly calibrating the hygrometer and checking the accuracy of thermometers are also important steps to ensure the optimal environment for chick development and hatching.

Eggs should be placed horizontally
The temperature and humidity inside a chicken egg incubator are critical factors in successfully hatching eggs. Incorrect temperatures and humidity levels can interfere with the normal growth and development of the embryo and even stop it from developing further.
To ensure the best chance of success, it is important that the incubator has a temperature and humidity alarm to alert you when the levels are out of range, as well as a thermometer and hygrometer to monitor levels. The ideal temperature for an incubator is between 37 and 39 degrees Celsius or 99.5 degrees Fahrenheit. Do not attempt to increase the temperature to speed up the process, as this will reduce the chance of hatchability and can result in abnormal chicks.
In addition to temperature and humidity, other factors such as egg position, eggshell quality, egg weight, and breeder age can also influence the success of hatching. It is also important to note that the number of chicks that hatch together is important, as chickens are flock animals and need companions to be happy.
