Well, you will need an incubator. You will need to keep this incubator between 99 to 101 degrees F, Humidity at 60-65, and turn the eggs three times daily.
You will need to get an egg that has been fertilized by a rooster (you cannot take one out of the carton in the fridge) and has not been cooled at any time. Place the egg is a false next of rags under a heated lamp. Keep it warm and it will hatch.
