If you are breeding birds or reptiles, you will need an incubator to hatch their eggs. An old refrigerator is easy to convert into a large-capacity incubator with multiple shelves for placing your clutch boxes. The insulation in a refrigerator's main compartment works very well to maintain a steady and proper temperature and humidity for your eggs. You can also use the freezer compartment, if it has one, to store extra supplies.

Lighten your load. Cut off or unscrew any unnecessary parts, such as the refrigerator's coils. Although this step is not vital, you will be glad you did when you need to relocate the unit later.

Drill a hole near the middle of the back of the larger refrigerator compartment.

Pull the power cord for the heat tape through the hole with a wire coat hanger so that the plug is outside the refrigerator.

Attach the heat tape in place with the aluminium tape. Secure the tape on the back wall of the refrigerator, near the centre for more even distribution of heat.

Pull the probe for your thermostat through the hole with the coat hanger and into the compartment.

Tape the thermostat probe as close as possible to the heat tape with aluminium tape.

Attach the probe of the thermometer and the body of the thermometer to different areas of the incubator with either tape or the suction cups usually included with this style thermometer. You want to monitor the temperature in different areas of your incubator to make sure it is consistent.

Plug the heat tape cord into the thermostat and adjust until your thermometer reads the desired temperature.
