However, they must be stored with the fat side of the egg pointed up to keep the embryo alive. Step 3 â Incubate. It takes 21 days on average for an egg to hatch once incubation begins. Before placing the eggs inside, turn on the heat source and measure the temperature and humidity over a 24-hour period, making adjustments as necessary to create the optimal environment.
