The humidity levels of chicken eggs during their incubation period are crucial to their successful hatching. During the last three days of this period, also known as the lockdown period, the humidity is increased to 65-75% to facilitate hatching. This increase in humidity softens the eggshell, making it easier for the chicks to hatch. In nature, humidity is increased by the hen during the lockdown period, but in an incubator, humidity is controlled manually.

This is to facilitate hatching and soften the eggshell
The humidity levels in an incubator play a crucial role in the successful hatching of chicken eggs. During the first 17 to 18 days of incubation, it is recommended to maintain a humidity level between 40% and 55%. This range can vary slightly, with some sources suggesting 45-50% or even as low as 30-40% for the first 18 days.
In the last three days, known as the lockdown period, it is essential to increase the humidity to the range of 60-75%. This higher humidity level facilitates the hatching process by softening the eggshell, making it easier for the chicks to break out.
To increase humidity during the lockdown period, there are several methods that can be employed:
- Add water to the incubator's trays. The greater the water surface area, the higher the humidity.
- Place a damp sponge inside the incubator.
- Close some ventilation holes to trap more humid air inside, but ensure some ventilation remains for oxygen exchange.
It is important to monitor humidity levels several times a day to ensure they are within the optimal range. Using a digital hygrometer can provide accurate readings, and it should be placed where it won't be obstructed by the eggs or incubator components. Regular monitoring helps catch and correct any deviations early on.

Ambient room conditions like temperature and humidity can affect the incubator's settings
The ambient room conditions like temperature and humidity can indeed affect the incubator's settings. The temperature and humidity inside the incubator are critical factors for successfully hatching chicken eggs. Therefore, it is important to place the incubator in a room with stable conditions, avoiding places with drafts, direct sunlight, or fluctuating temperatures.
To maintain consistent humidity levels, it is recommended to keep the incubator in a room with steady ambient temperatures, free from drafts, and shielded from direct sunlight. This is because higher temperatures accelerate evaporation, impacting the moisture exchange between the embryo and the air in the incubator. As a result, the humidity levels inside the incubator can be influenced by the ambient temperature of the room.
Additionally, the humidity in the room can also affect the incubator's settings. High humidity in the room can cause the incubator's humidity levels to rise, especially if there is insufficient ventilation. Wet weather outdoors can contribute to increased humidity levels in the incubator. Therefore, it is crucial to ensure proper ventilation in the incubator to regulate humidity and provide sufficient oxygen to the embryos.
To achieve the optimal humidity range for successful hatching, it is recommended to maintain a humidity level of 45-55% during the first 18 days of incubation. This ensures that the eggs lose moisture at the correct rate, which is crucial for proper embryo development. During the last three days, known as the lockdown period, the humidity should be increased to 65-75% to facilitate hatching.
It is worth noting that the porosity of eggs varies with size, age, and season, which can impact the required humidity levels. Additionally, different sources may suggest varying levels of incubation humidity. Therefore, it is important to monitor humidity levels closely and make adjustments as needed to ensure successful hatching.

The humidity level for the first 18 days is typically between 45-55%
Maintaining the correct humidity in an incubator is critical to successfully hatching chicken eggs. For the first 18 days of incubation, the humidity level should be maintained between 45-55%. This range ensures that the eggs lose moisture at an appropriate rate, which is crucial for proper embryo development.
The humidity level during this period can be monitored using a digital hygrometer, which provides accurate readings. It should be placed in a position where it won't be obstructed by the eggs or incubator components. It is recommended to check the humidity levels several times a day to ensure they remain within the optimal range. Additionally, ambient room conditions, such as temperature and humidity, can impact the incubator's internal settings. Therefore, it is advisable to keep the incubator in a room with stable conditions, avoiding drafts, direct sunlight, or fluctuating temperatures.
Some sources suggest that a humidity level of 40-50% during the first 18 days is also acceptable, while others recommend a range of 30-50%. However, it is important to note that humidity levels below 45% may hinder proper embryo development. One source mentions that they had their worst hatch ever when maintaining humidity levels of 50-55% during the first 17 days.
To achieve the desired humidity level, you can add water to the incubator's trays or place a damp sponge inside. The greater the water surface area, the higher the humidity. However, it is crucial not to exceed the recommended humidity levels, as too much humidity can be detrimental. High humidity can result in smaller air cells and oversized chicks, making it difficult for them to hatch.

The surface area of the water determines the humidity level
When it comes to increasing humidity for chicken eggs in an incubator, the surface area of the water is indeed a critical factor. The larger the surface area of the water, the higher the humidity in the incubator. This is because water evaporates from its surface, and a larger surface area allows for more water to evaporate, leading to increased humidity.
To increase the surface area of the water in an incubator, you can use trays with multiple channels or add damp sponges. By increasing the number of water channels or sponges, you can effectively increase the surface area, which will result in higher humidity levels. This is a more effective method than simply adding more water to a single container, as it is the surface area that is the key factor in determining humidity levels.
Additionally, the amount of water vapour that can be present in the air depends on the temperature. Warmer air can hold more water vapour, which is why the hottest days of summer tend to have the highest humidity. Therefore, the temperature of the incubator will also play a role in determining the humidity level.
It is important to monitor humidity levels in the incubator regularly, as too much or too little humidity can negatively impact chick development and hatching. The ideal humidity range for the first 18 days of incubation is 45-55%, and during the last three days, this should be increased to 65-75% to facilitate hatching.
In nature, humidity is primarily influenced by the evaporation of water from sources such as oceans, lakes, rivers, plants, and the ground. The amount of water vapour in the atmosphere, or absolute humidity, is a key factor in determining humidity levels. The higher the absolute humidity, or the amount of water vapour in the air, the higher the humidity. This is similar to how the surface area of water in an incubator affects humidity levels.
