Our incubator is set up on a stable table near a power point. We need the power for the heating element and the fan inside the incubator to work. A thermostat ensures the temperature remains at a constant level by turning the heater on and off. We can tell how warm it is inside by looking at the thermometer. The temperature needs to stay at 37.5 degrees.
In the incubator, behind the fan is a plastic container. This container is filled with water. The water in the incubator is very important. The water together with the heat creates humidity. The humidity helps keep the egg shell moist. The moisture softens the egg-shell, which makes it easier for the chicks to hatch.
