All year I have had pretty poor hatches.. Well this morning I walk in to check on the incubator, day 19, and the windows are dewed! I lift the top off and the temp is 80! I panic and look around.. A chair had falled over on the cord I dont know how long they have been like that. I checked them late afternoon and the temp was about 99-100. The temps have been about 102-104 in the still air. I candled night of day 17 and I had a few clear and some so dark you could only see the veins on the very edge. Being at 80 for lord knows how long.. Have I failed?
I would keep trying to incubate them... there pretty hardy little things. If it helps i bet I'm worse at incubating then you! my best hatch was 50%
I'm going to count this as a temp spike in the low direction instead of the high direction... I'd personally keep them in the incubator and wait to see. My eggs get 80-90 degrees for a few minutes every day while I wet down the paper towels I keep in for humidity. I imagine there are times in nature when a momma hen was away from the nest for a bit and the eggs cooled some and were ok. Maybe yours will be a success story! I'm also interested, as this is a different sort of spike, in what your hatch ends up like. We're keeping track of temperature spike stories here: https://www.backyardchickens.com/forum/viewtopic.php?id=358298
I would wait and see. I had a broody leave a nest due to a heatlamp incident and the eggs had 4 days to go. They were cool to the touch when I found them. I put them back under her and 8 out of 10 hatched! Good Luck!
I too think you have a reasonable shot. I've heard several say they purposely drop the temp (although not that far ) during lockdown. I am no expert but I believe they could handle a lower temp better than a high temp spike.
I heard cheeping!! ...but I dont know if my humidity is high enough. I noticed that my meter is off I know its at atleast 40%
