incubator issue - worried about eggs

[denice213]

I have an incubator that I have used for hatchings and it worked well for the first time or two but the last time I used it, I had a very low hatch rate which before, I averaged 80%. I put a second batch of eggs in and we are on day 20. I have paid attention to temp and humidity and I noticed that I had no early PIP's which I always do. The reviews on my incubator were lack-luster on the accuracy of the temperature so I used a few other monitors to check the temp and they ranged from 104 and up. My incubator showed it was maintaining 99.5. Devastation hit so thinking they were fried I candled them and no movement at all was noticed in any egg. The incubator started blinking and stopped warming the eggs for about 6 hours. I turned it back on and it started working to heat the eggs up.
What is the survivability of the eggs at this point?

Welcome to BYC!
How long did it run at 104 degrees?

i did not check temp after lockdown. I am not really sure how long it has been.

Have you candled the eggs?

i used a celsius glass thermometer and it read 40. another one read 105, a reptile one kept inside said 100

yes with no movement. i took one egg out and opened it. the chick was nearly lifeless after the incubator was off. I quickly put that chick back in and turned incubator on, reset it so it cleared its issue and started warming again

Have any pipped internally yet?

 

[denice213]

No pips and I always hav at least one by day 19

Because of no pips that is what alerted me to a issue
