Instructions
Examine the eggs before incubating. Discard any eggs that are cracked or have thin shells.
Mark each egg with an "X" on the one side and an "O" on the other.
Turn on the incubator and allow it to heat to 100 degrees Fahrenheit in forced-air incubators and 102 degrees in still-air incubators.
Place the eggs in the incubator and mark your calendar on when they were put in. Lay the eggs to the pointed side slightly angled up, but that each egg is predominately on its side. The embryo will grow in the more narrow end where it is easier to break the shell upon hatching.
Maintain the humidity in the incubator by adding water as needed to a dish or the humidity tray (if your incubator has one). This should be around 55 to 60 percent humidity in the first half of incubation moving to 70 percent just a few days before hatching.
Turn the eggs four to six times daily. Some incubators do this manually. Otherwise, mark your calendar with the times you placed the eggs "X" up and the turned them to the "O."
Count the days of incubation. It should take 22 to 24 days for most breeds of fowl. Check the development by using a light or candle to look for the embryo shadow.
Discard eggs that have no development in the last week of incubation to prevent rotting and disease afflicting the other eggs.
