I went to bed and the temp was 100. We are in PA and had massive snow and a cold front over night but I assumed the temp would stay the same in the incubator - no, it did not. I wake up at 7 AM and the temp is about 94-97 (I freaked so I am not even sure) and not sure of how long it was that temp. Was very close to them hatching; would this have killed them? Sad and ticked at Mother Nature and Myself, Michele I recently posted that on Friday I heard scratching in the eggs (by placing my ear near the incubator) then Sat no sounds but one egg sort of moved quickly and that was it - then last night I see what looks like a hairline fracture on one egg (I expected a hole not a crack) - Not sure what these signs mean either.
