Ok so I have a similar question - in my case, the incubator wasn't unplugged and we didn't lose power. BUT!!!! I have had a few eggs hatch, and been taking the babies out to put them in the brooder (have about 30 eggs or so in the incubator - 6 have hatched so far). My question is - it seems like the eggs are not as warm as I would expect them to be and I had candled the eggs and the vast majority looked to be developed. If the temp got a little low for a few hours, and it comes back up - would this just delay some of those eggs from hatching? I think it's day 21/22 for most of them. There are some eggs that were set in a different incbuator 3-4 days later that were combined with the others in this incubator so I know they aren't ready just yet.
But I am wondering, since I have had 5 hatch (one as recently as a couple hours ago) there is still a chance that the rest should be ok, yes?
