    The last few hatches from shipped eggs I have had 3/9 4/9 1/4 2/7 2/12 3/9 hatch. The second number was not the eggs set, but the eggs at lockdown. This time I put 28 eggs into lockdown, 7 hatched, but one is fat and can't stand. Temperature was at 99.5 in a still air with 60-65% humidity. The temperature did dip half a day to 97-98 when someone changed the house thermostat. The eggs were set at 99.5 in a forced air incubator using the dry hatch method. I cleaned the incubator out with white vinegar the week before. Could the cold weather be doing this? I just blamed that until my home eggs only hatched 3/9 (they usually are ~100%)

    Using Little Giants

    I eggtopsied the last hatch, 3 internal pips 3 died early and 3 external pips not hatched. The rest were fully formed, dead in shell. Some were starting to blacken.

    First off shipped eggs almost never hatch well. Plus you have a till air incubator. Those create an unequal environment for the eggs. I would add a fan and see if that helps circulate everything.

    Isn't it bad to hatch with a fan?

    No mine has a fan and I always get good hatches. Most of the more expensive incubators have fans in them.

    I think I would check your humidity maybe calibrate it. If its making it to pip more likely a humidity issue than a temp issue. Eggs at the hatching stage have more tolerance to temp differences and less tolerance to humidity changes.

    There is a salt test somewhere on here. Try searching calibrate hydrometer in the byc search box.
