I'm going to sub here... even if my next hatch is a little after April... probably first week of May if I can get my eggs here and set in time. I do have a question though? What would make a chick completely develop and then die right at the last moment, without even pipping?
Welcome! Whatcha got cookin?
Several things can cause them to quit very late.
Incorrect humidity throughout incubation can cause them to be too large or too small to hatch.
They can get in the wrong position and not make their way out.
Improper ventilation.
They can have physical defects that can cause them not to hatch.
Temp fluctuations...
The list goes on...
Joining the April hatch-a-long. 53 eggs. 24 araucana 28 ayam cemani. One jersey giant/ayam cemani mix (just want to see how it looks, planning on eating it eventually).
My last hatch was terrible. Only about 33%. I do believe that humidity was a problem with the dry winter air. My incubator just are through water like crazy. And we have radiator heat.
This was evident to me when two of my eggtopsies showed completely shrink wrapped chicks. Fully developed.
Now that it's warmer and the furnace isn't on so much I should be a little better.

Awesome! Good luck!
Check your seal around the edge of the bator, maybe its not sealing completely?
