Biggest temp spike or drop??

[Morri]

Ok so i am a beginner and just set my first batch of 5 chicken eggs and it was a hot day today and the temp got to 101 but its back to 99.5 now will they be ok???

JUst a random question what is the highest spike or lowest drop in temp in the incubator someone has had chicks still hatch and survive???

Thanks

they'll be fine. it is long term variation from the desired range that i think hurts. another BYC'er posted he had most of his eggs hatch after a spike to 104F. it probably has a lot to do with the stage of development.

the anxiety seems to wane around day 13 or so. it gets easier but then they "pip" and one's anxiety spikes again.

I'm having a serious temp problem myself. I bought another bator jut like the one I already have which is a LG and got turners for them both. I didn't have a big problem with temps before in my other one the past year but since I put in the turners it has been a real pain in the backside. I've hardly gotten any sleep from babysitting the bators. Right now the older one has chicks hatcing in it and the turner is out and the temp is stabilized. On the other hand the new one with all the new turner and thermometer/hydrometer is going wacko. It has spiked up as far as 104 and as low as 98.4. It will stay at 98.4, but when I try to get it to 95.5 it just keeps climbing. Just a little while ago I discovered the battery is bad in the new thermometer. So I put the older one in since that bator is doing fine. But the temps are still low. Is it safe to let it stay at 98.4? I have eggs in it that are from a week to 2 weeks into incubation. I really don't want to loose these eggs but I fear that's too late already.When these chicks hatch I can put the eggs in the older bator and return the new one for an exchange and pray it works better. I have shipped eggs that need to go in by friday. I have to have this temp problem solved or i've got a long 3 weeks coming.

But for now, is it safe to let it stay at 98.4? I usually let it get between 99.5 and 101.0 any higher or lower and I make adjustments.

98.4 should hatch.


I proved just this week that they can survive 104 for 12 hours(day 17).
I also know from my own experience that 106 for about an hour is survivable.
On the cold sided... Last year I had a 24 hour power outage. My big incubator is a fridge outside in the weather. Snowing on the incubator, an no power for 24 hours an they still hatched.

Thank you for reassuring me with your post. I had a 104 spike for who knows how long between 3am to 8 am. Tomorrow is lockdown, so we will soon see.
