Instructions
Obtain duck eggs that have been fertilized.
Ensure that a proper incubator has been purchased or built. Incubators can simply be any enclosed box or area that can retain heat and has easy access to the eggs.
Make sure the temperature of the enclosure or incubator stays at approximately 99 to 99.5 degrees F for the first 25 days. Reduce the temperature to 98.5 degrees F on day 25 and allow incubating for an additional 3 days.
Control the humidity of the incubating duck eggs for the first 25 days to 86 percent. Adjust the humidity to 94 percent for the remaining 3 days.
Turn the duck eggs an odd number of times per day throughout the first 25 days. Three, five, and seven times are a common process. This allows the hatching duck eggs to "rest" in differing positions. Stop turning the duck eggs over the last 3 days.
Consider candling (placing a small, very bright flashlight at the top of the duck egg and shining light through) the duck egg after 7 days to check on the fertilization process.
