I read on Ron's digest that someone lost eggs to a faulty thermometer.
I have as well. I set 14 Comet eggs and 4 Leghorn eggs, and they did alright, but I had quitters along the way. It was my first hatch.
I locked down 8 eggs, and switched thermometers. I egg-topsied the seven that didn't hatch. According to the assisted hatching article (link in it to a university study), they had gotten too hot during lockdown.
I found out after the first 36 hours of lockdown that the thermometer I was using was reading 90-ish when the temp was really over 102*.
We named our lone hatchling "Little Red" and we're keeping him/her no matter what (even though I was going to cull all my cockerels). I just can't cull my very first hatchling!
To those who have lost eggs, chicks, etc:
