Can you please tell me something. I saw where you have done a dry hatch for duck eggs. My cheap incubator gets down to 10 on humidity. Isn't that too low if I don't add water? When I do add though even if it is a small amount it goes up into the 70's. My one egg pipped at 18 days and was dead. Can you please explain how low yours has gotten and if it mattered or not, thanks in advance, I really appreciate it.
