The poultry incubator is a device used to simulate the natural incubation process of eggs, in order to hatch them into chicks. It is commonly used in the poultry industry and by hobbyists who raise chickens, ducks, and other poultry.

Poultry incubators can come in different sizes and designs, but the basic components typically include a temperature controller, a humidity control system, an egg-turning mechanism, and an egg tray. The temperature controller is used to maintain a constant temperature inside the incubator, typically between 99 and 100.5 degrees Fahrenheit (37.2 to 38 degrees Celsius), which is the optimal temperature for incubating most poultry eggs. The humidity control system is used to maintain the appropriate level of moisture in the incubator, usually between 50 and 55 percent humidity.

The egg-turning mechanism is used to mimic the natural behavior of mother birds, which would turn their eggs several times a day during the incubation period. This helps ensure that the developing embryos do not stick to the inside of the eggshell and also helps distribute heat evenly. The egg tray holds the eggs and is designed to allow the eggs to be easily turned by the turning mechanism.

Poultry incubators require careful monitoring and maintenance to ensure that the eggs are developing properly. It is important to regularly check the temperature and humidity levels and to turn the eggs several times a day. The incubation period varies depending on the type of poultry but typically lasts around 21 days for chicken eggs.
