Power out 3 hrs, dropped to 85F at day 2 /day 10, what are my chances?

[exop]

Hi everyone. Help - I need reassurance! Or to know the grim truth, if there's no reassurance to be had.

My incubator, a new hovabator in a 70 degree room, was unplugged for 3 hours today. When I discovered it and plugged it back in, the air temperature in the incubator read 85 degrees F.

This incubator contains 1 set of eggs that have been incubating for 10 days, and one set that have been incubating for 2 days.

What can you all tell me about my chances for survivors, in each group?

This is very upsetting, as the 2-day set contains some esoteric hatching eggs that I had been waiting for for a month, expensive la, and the 10-day set contains some eggs from a special breeding I had set up with a pair of my own chickens, who were isolated together for weeks to produce these eggs

As I write, ~ 30 minutes after fixing the plug, I see it's risen to 95 degrees F.

Please, please please let things be ok.

I'd think they'd be okay. The older the egg the more affected but cooling down is much safer than overheating. Probably not going to see much of a change in that short a period. High heats above 103 for prolonged periods are vastly more dangerous. Good luck.

Dude that sucks..... sorry, I hope they all survive.

probly they will be fine
Good luck

we had a power outage for 2 maybe 3hrs
not sure so i wrapped
bator in a blanket. and the temp drop to 85

I have BCmarens that i have been wating for like it seems forever LOL
and hoping they hatch on or after mothers day. and white siklies
and buff orp.
lets hope we both have a good hatch..

DON'T THROW THEM OUT! They will make it probably. I threw out 60 eggs after a power outage and later found out from the knowledgeable BYcer's that as long as they don't overheat most of the time they will be o.k.

should be fine. I moved my broody about a week into incubating, I always let her out about 8 'o'clock but I had to wait to show her were her nest was after she was done eating drinking and reliving herself. She started going back to her nest on her own... so I didn't think I need to watch her anymore. well the next morning I came out around noon and saw her brooding in her old spot....

6 out of the 7 hatched fine. and the temp had to of dropped to around 40 degrees.

I opened the incubator in a panic when I realized what had happened, and found the eggs were cool-ish to the touch

Now the incubator is up to temperature... with luck the eggs will be getting there soon.

I just tried to find out what stage the 10 day old eggs would be at, and came up with these interesting yet depressing links about embryo development and pictures of the stages:

Here's day 10

Hard to believe that something looking so much like a chick can cope with having its body temp dip down like that.

Thanks, Fancie217 for giving me some reason to stay positive! Day 7 looks pretty important too:

Apparently the heart starts to beat at hour 12 of incubation (!)
How about that.

Thanks, everyone, for your help!

One of the 10-dayers pipped yesterday, hatched this morning; another pipped today. I have my fingers crossed.

Gail Damerow writes, in Storey's Guide to Raising Chickens, that in case of a power outage,

...Open the incubator and let the eggs cool until the power goes back on. ...A power failure of up to 12 hours may not significantly affect the hatch (except to delay it somewhat), especially if the outage occurred during early incubation, when cooled embryos naturally tend to go dormant.

Seems totally counterintuitive.

She warns that if you do try to keep eggs warm, make sure they get enough oxygen... Anyway, I hope this means things will go well with the 2-dayers.

In celebration of my new arrival, here's a new Silkie jumpy:

Best - exop​

Hey thats great, if the 10 day olds could do it the 2 day olds should have plenty of hope. Best of luck.
