Roast in a 325 degree F oven for 15 to 20 minutes. The seeds will not change much in color, but will crunch when done. A note about salt: We use kosher salt. If you donât have it on hand, keep this in mind: 1 teaspoon fine sea or table salt = about 1 1/4 teaspoons kosher salt.
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.
At the end of the incubation period (about 21 days), the eggs, if fertile, will hatch. Development of the egg starts only when incubation begins, so they all hatch within a day or two of each other, despite perhaps being laid over a period of two weeks or so.
