Building a DIY incubator requires a few essential materials and basic construction skills. Farmers can start by obtaining a sturdy cardboard box that is large enough to hold the desired number of eggs. The box should be lined with a heat-resistant material such as foil or insulation foam to help retain the heat. A light bulb or heat source can be installed inside the box to provide the necessary warmth for incubation. To regulate the temperature, a simple thermostat or temperature controller can be connected to the heat source. Farmers should also ensure proper ventilation by creating small holes in the box to allow for air circulation. Regular monitoring of temperature and humidity levels is crucial to ensure successful hatching.
