I have 7 duck eggs in the incubator, I had a good temp of 99.5 for the past two weeks, 2 days ago I added water when it was low and suddenly maybe 12 hours later I saw the temp was 101.6! I opened the incubator, turned it down, and then readjusted temp. I just candled my duck eggs, they're at 16 days today and I didn't see any movement, I am having a hard time giving up on them, I plan on candling later again when it's dark, is 101.6 absolutely fatal?
