Ok I have 6 (2-3 fertile i think)eggs due the 26 and then 18 due the 2 of may. I am concered that infertile eggs will explode due to the heat and time. I know I am not good at candling so this is an issue for me. And second this is a staggered hatch. If i put the humidity up to 65% the last three days for the 2-3 eggs that means I will have the humidity up the last 6 days for the 18 eggs. Will that be to high for the for the last 6 days for my 18 eggs. I would rather have 18 eggs hatch rather than two or three.
