Well it was Day 27 so I gave up and eggtopsied the eggs that hadn't hatched. I originally set 38 eggs. When I did the eggtopysy's there were - 3 that had very small chicks in them about the size of my thumb with a huge yolk, 5 of them were fully developed and had started to absorb the yolk, 9 were fully developed but hadn't absorbed the yolk, 9 weren't fertile or died early on, and 8 of them were small about the same size as their yolk. 4 of them hatched. One of the ones that hatched didn't fully absorb his yolk and it was hanging halfway out. He died less than 48 hours later. I was using the dry hatch method so I believe the humidity was somewhere around 35-45% humidity until day 18 when I added water and it went up to 55-65% humidity. I am using a new LG still air with a digital thermostat. I have a wood stove for heat and a swamp cooler so my home's temps don't exactly stay steady. I wrapped my LG in a blanket to help insulate it. Why do you think so many chicks died so late in the game?
