#6 pipped a bit ago. This is what I'm used to with the Delawares, most hatching by the time Day 21 rolls around. That darn Flukers thermometer was the cause of the less than stellar hatch last time. It read too high and made me turn down my thermostat. This time, I used it only for humidity and it has read 101.5-102.5 the entire time. If I was depending on that, I'd have turned down the heat too low. So, those units you put in the bator, as I've always said, will lose accuracy after a few hatches.
Incubators will get you in trouble, Reva, LOL. I usually like to wait for a broody, but you can't put 30 eggs under a broody, even the big girls!
