My mom gave me 12 call eggs, and six started developing... One by one they are all quitting. I am doing something wrong for ducks, I am down to 2. *cry! Now I know why there are whole threads dedicated to hatching these little buggers.
Awww. I'm sorry to hear that. They are tough to get to hatch. Maybe check humidity and temp with another hygrometer/thermometer to make sure the one you're using is reading correctly. Everyone incubates differently but I incubate at 20-30% humidity and 100 degrees. I do not add any water during incubation and then add it at lockdown to raise humidity to 70-75%. The last time I heard of someone loosing that many before lockdown was because her hygrometer was off
