I always have trouble getting the air flow exactly right in the hatch tank. The male does a perfect job of aerating the eggs and keeping them fungus free.
You may want to let this batch go and use it to establish exactly how many days to hatch and how many days between laying. Then you can remove the eggs the night of the hatch to the hatch tank, reducing the chances of problems with the eggs, and wake up the next morning to babies!
I agree with Greg on the Wilkerson book. It is an excellent reference and tutorial.
