Egg incubators work by providing a controlled environment that mimics the conditions a broody hen would create to hatch eggs.
They maintain a consistent temperature, usually between 99 and 102 degrees Fahrenheit, and humidity level, usually between 40 and 60 percent, while also providing ventilation and sometimes turning the eggs to prevent the embryos from sticking to the shell.
The eggs are placed in the incubator and monitored until they hatch, which typically takes around 21 days for chicken eggs.

The ideal temperature and humidity for egg incubation can vary slightly depending on the species of the egg being incubated, but for chicken eggs, the ideal temperature is around 99 to 102 degrees Fahrenheit (37.5 to 38.9 degrees Celsius), and the ideal humidity is between 40% to 60%.
The temperature and humidity should be consistent throughout the incubation period to ensure healthy embryo development and successful hatching.
It’s important to follow the manufacturer’s instructions for your specific egg incubator and monitor the temperature and humidity levels regularly to ensure they remain within the recommended range.

The length of time it takes for eggs to hatch in an incubator can vary depending on the species of the egg.
For example, chicken eggs typically take about 21 days to hatch, while duck eggs take around 28 days and quail eggs take around 17 to 18 days.
It’s important to know the incubation period for the specific species of egg you are hatching and to monitor the eggs regularly throughout the incubation process to ensure healthy embryo development and successful hatching.

Many different types of eggs can be incubated in an incubator, including:
Chicken eggs, Duck eggs, Quail eggs, Turkey eggs, Goose eggs, Pheasant eggs, Peafowl eggs, Parrot eggs, Reptile eggs (such as snake, lizard, and turtle eggs) and some types of fish eggs.
It’s important to know the specific requirements for the species of egg you are incubating to ensure proper incubation conditions and successful hatching.
