Update: The baby didn't make it. I'm going to go ahead and say this one was my fault. Looking at the embryo, the chick seemed to have formed correctly and just needed time to absorb its yolk. I also had tghe day wrong - yesterday was day 21, not day 20 (meaning today is day 22).
I think the power outage must have messed with their metabolisms or something, because they should have already absorbed the yolk and moved into position by yesterday. If I had been more patient and not messed with the egg, it probably would have hatched, just a day or 2 late.
I will say, though, that chick did appear fairly weak. It was moving at 5am today and seemed like it was getting into position. I opened the egg the rest of the way right now when I saw it had stopped moving entirely. It's head was still on the pointy end of the shell. I don't know if leaving it alone would have affected anything, but I can say this was definitely a learning experience.
Thanks everybody for your well wishes! I have more eggs that start lockdown today. I might post pics or videos in a few days if things go well.
I'm sorry it didn't make it! Fingers crossed for your next hatch. Just keep I mind that absorbing the yolk sac is one of the last things the chick does before starting to unzip the shell so be patient with the little ones. Hatching is hard work and it's not uncommon for them to rest for hours in between piping internally and externally. Good luck!
