Thursday I will move the Muscovy eggs from the rack to the bottom of the incubator. It is a forced air one that holds about 150 eggs. I just put in three more racks of Muscovy eggs and chicken eggs combined yesterday. I had 14 out of the 20 chicken eggs hatch last Monday, the ducks will be soon. I read that duck eggs like a higher humidity and someone recommended putting a paper towel under the duck eggs. What about a moist towel, would that work too? Have that wonderful and beautiful day, Cynthia.
