Out of 12 eggs zero ducklings! Last candling, three days before hatch date showed 4 live and moving ducklings. One tried to hatch, but died. Today is day 28 and no movement or peeping. I used Hova 1588 with the fan blowing all the time. Temp was around 99.5 and humidity at stable 70% for the duration. There is no way to up the humidity in this incubator because of the blowing fan, regardless how much water I put there. Eggs were on their sides and I turned three times a day religiously. Should have I used still air incubator? I have not misted the eggs, as I learned about that only recently.
