Should I spray my duck eggs?
The eggs should be left so they feel neither warm nor cold to the touch. Then mist each egg with lukewarm water and replace the incubator lid. The misting helps keep the humidity levels high and the membrane moist which assists the duckling in hatching.
How long can a duck egg survive without heat?
