How to hatch turkey eggs in an incubator
Set up your incubator at least 24 hours before you put the eggs in.
Fill the lower channel with water to ensure adequate humidity.
Place two thermometers in the incubator.
Make sure they are elevated to half the height of the eggs (usually about 1 inch). You can get disposable plastic cups and cut them to the desired height to act as platforms for the thermometers.
