Are you having good hatches with other breeds you are hatching? If so then your incubator and sanitation are probably good.
Other questions I can think of:
How inbred are your lines? Are you doing full sibling breeding?
How many breeders male and female do you have? Is it one rooster and many hens or more than one rooster? If it is one rooster I would try a different one. If it is only one hen I would try a different one.
When things go like that I just keep changing things up until I get it to improve.
My latest... is last week my Johan #1 pen went on strike and not an egg all week. I haven't changed a thing, no molting, weather is perfect, same diet. Only thing that is different is my lead bird got her foot caught in a space in the nest box and twisted it pretty bad. I had to free her in the evening when I found her. She spent two days in a sick bay and is back on her feet. Maybe they are afraid of the nest box. Crazy birds, I don't know why I put up with them sometimes.
