I had a longer outage than that on day 14 (maybe up to 20 hrs) and they were at 60ish deg when it went back on. All the eggs hatched fine, just about 18 hrs later than I was expecting them to start. Don't give up!! That close to hatch they seem to be quite resilient.

=) Thanks. Good to hear.
I keep reading and rereading that Brinsea temperature study.
If I was going to crash and burn at this, I told myself I didn't want it to be in the late stages when there's very developed chicks in there.
But for that matter, at least they're big enough to be generating some amount of body heat and they're sitting close to each other. Hope they kept each other warm.
