So, after 25 days in the incubator, I finally gave up on my 5 "duds" (my first time incubating, and I was using a borrowed incubator). My husband cracked them open (I didn't want to see any dead chickies), and all 5 of them were liquid inside, one of them popped when he cracked it and smelled HORRID like rotten eggs. At lockdown on day 18, I put my own thermometer inside the incubator next to the eggs (it was a room temp/humidity thermometer I used when the kids were babies), and discovered that the temp inside the incubator was about 2.5 degrees lower than the incubator screen was reading, and the humidity was about 15% higher. They were mail order eggs from Murray McMurray, and I find it hard to believe that ALL 5 were unfertilized, so I'm assuming that the low temp was the issue? Do the results of the eggtopsy confirm low temp as the culprit? When I put my own thermometer inside, the temp was measuring 96 degrees.
