No, a fertilized egg will not hatch if it is put in the refrigerator. In fact, placing a fertilized egg in a refrigerator would likely prevent it from developing and hatching. Fertilized eggs require specific conditions, such as proper temperature and humidity, to develop and grow into chicks.
If you want to incubate and hatch fertilized eggs successfully, you need to provide the eggs with the appropriate conditions. This typically involves using an incubator that can maintain a constant temperature, humidity, and turning the eggs regularly to ensure proper development. The incubation period for different bird species varies, but it usually takes several weeks for the eggs to hatch.
Refrigeration is not a suitable environment for incubating eggs, as the low temperature will inhibit the embryo's development, effectively stopping the hatching process. If you have fertilized eggs and want them to hatch, it's essential to follow proper incubation procedures to give them the best chance of successful development and hatching.
