No, I guess I need to read more about how to properly hatch duck eggs. I put them in the incubator set the temp at 99.5 and humidity in the 50's and 70's during lock down. I didn't realized I needed to spray water and cool them down. I guess it makes sense because mamma duck usually are wet for swimming.
Below are some instructions quoted from a website. When I spray the eggs I leave them in the incubator and just leave the lid off. I spray the eggs and leave it open long enough for the water to evaporate and then I close the lid again. That was the easiest process for me.

"Sometimes a regime of cooling and spraying duck and goose eggs results in better hatchability. Start after about 10 days of incubation. Open the incubator or remove the eggs so they cool. If you have an infrared temperature gun, cool the eggs until the shell surface reaches 86 degrees. If you do not have a way to accurately read the temperature, hold the egg to your eyelid. If it feels warm it needs more cooling, if it feels neutral you are done cooling, if it feels cool you have cooled too long. Then you can spray the eggs with room temperature water and return them to the incubator. The incubator should be able to warm up in about the same amount of time it took to cool the eggs. Do not spray and cool after day 25. The actual consequences of spraying is interesting. One consequence is it changes the membrane of the egg so a greater percentage of moisture is lost during incubation. Ideally a duck egg loses about 13% of its weight between the time it is laid and day 25 of incubation. Losing significantly more or less than this reduces hatchability."
