Not a great day. First I think I have to throw out the eggs under my broody hen because she left the unattended for 4 hours (different post) and start again. Then tonight I candled the 26 eggs in my incubator and realized that I was kidding myself that there was something alive in there. I just cracked them all open and no development. This is the second time in a row this has happened. The strange thing is that my first hatch in this incubator I had an 85% success rate and got 29 chicks. Same hens and rooster and I know my eggs are fertile (little doughnuts visible on yolk). I checked my thermometer on a regular basis and it was staying steady at 100 (well, it drops slightly and then reheats, so mostly 100). I am now starting to suspect that while it may have been a steady temperature that the thermometer is not reading properly. It's the one that came with my Havabator and pretty basic. What do you think? I am totally depressed since I had been so careful with this batch after the last total failure.
