Things You'll Need:
- Incubator
- Duck eggs
- A bright light
- Duck incubator insert tray
- Incubator-hatching basket
- Step 1
Set the incubator to 99.5 degrees Fahrenheit and 55% humidity. Leave it on for a day or two to stabilize the temperature and humidity levels before placing the eggs inside. Set the ventilation by reading the incubator manufacturer's directions.
- Step 2
Select eggs that have been laid 1-3 days prior and are not misshapen or too big or too small. Inspect the eggs by shining a light through, or "candle," the eggs. If you see double yolks inside or notice any cracks, do not select these eggs.
- Step 3
Place the eggs inside a duck incubator insert tray and place the tray inside the incubator. Turn the eggs four-to-seven times each day.
- Step 4
Candle the egg after the sixth day of incubation. At this point, you should start to see spider-like veins developing around the egg. This is a good, fertile egg that is developing normally. Discard the bad eggs.
- Step 5
Remove the egss after 25 days from the egg tray and place them inside a special incubator-hatching basket. Candle the eggs again at this time to see if the egg is developing normally. Discard any eggs that have dead embryos.
- Step 6
Set the incubator to 99 degrees Fahrenheit and 65% humidity for hatching. Increase the humidity level to 80% and increase the ventilation so it is set at halfway as the eggs begin to hatch.
- Step 7
Lower the temperature gradually to 97 degrees Fahrenheit and the humidity to 70% when the ducks are mostly hatched. Ventilate the incubator to maximum capacity. Remove the ducklings when they are mostly dry.
