Hi Gary:
  
Some eggs are better than olthers.  
If these are the same eggs that were fine prior,
try and find out what is different.
Is it posible your room was warmer previously?
Mine normally hatch best at 80-82f.
I never use more than a teaspoon per gallon.
Sometimes a newer finer mist airstone is the culprit.
Sometimes the water is lower pH from the source in municipal.
During low water season more clarifiers are added.
They tend to reduce the pH (sometimes 7.0 today yet 6.0 in 24 hours).
I like to add a little Epsom Salts and Bicarbonate if Soda to get pH to 8.0.
Even when cans are from the same case wuth the same lot numbers,
their may be a great difference in the eggs.
Some leave eggs in freshwater too long before adding salt.
I have found Ocean Nutrition nitrogen pack eggs the very best.
But hatch changes if they get too warm (even as an egg).
I don't ship common carrier in hot summer months.
Heat can definately weaken an eggs hatched months later.
If possible check 'alkalinity'; of low boost.
Normally survival is better at 8.4 than only 8.0 pH.
