How to Build an Egg Incubator

There are three basic types of artificial egg incubators. Still-air incubators rely on radiant heat. Convective heat incubators provide circulation of heat and air through passive ventilation. Forced air incubators use a fan to circulate air and heat. Each type requires careful temperature control and humidity for successful hatching and survival of chicks.

  1. Putting it Together

    • 1
      An incandescent bulb will provide heat for the incubator.

      Cut a hole for the light. The light will provide heat. Use a drill, saw or knife to cut a hole that fits the light bulb inside the box, with the switch and socket for the light outside the box. Make sure the light bulb does not contact any part of the box that may be flammable.

      Reptiles as well as birds can be hatched in incubators.

      Plug the light into a dimmer switch. You will use the dimmer switch to control the temperature inside the incubator.

      Cut or drill ventilation holes. Make holes about a 1/2 inch across. Place holes in the side from the top to bottom, about two or three per square foot.

    • 4
      Place the bulb of the thermometer at the same level as the eggs.

      Place the thermometer and the bowl with water inside the incubator. The thermometer should be placed as close as possible to where the eggs will be placed.

      Turn on the light and adjust the temperature. Allow the light to run at a constant dimmer setting for a few hours, then check the temperature. If it is too hot, dim the bulb and check the temperature in an hour or so. Adjust until the desired temperature is maintained.
