Unlike when a mother hen does it, the machine won't know that an egg is starting to hatch, and either a hatching egg or a hatched chicken could be badly damaged by the egg turner. Also, the humidity drops *fast* when the incubator is opened, which can dry out exposed membrane.
Our third chicken yesterday started getting shrinkwrapped. She was the second to get her beak out but then she got stuck. We tried a little coconut oil on the exposed membrane but it seemed not to help. We gave her some time and came back, and even at 70% humidity her membrane was clearly tight...
Another thing that only clarified in my mind very recently: internal pipping is when they get into their air sac. When they do this they can start peeping. External pipping is when they break the egg from the inside. Zipping is when they work their way around in a line to pop off part of the egg...
#4 is breaking more of her egg, and one of the previously-quiet eggs has started rocking. This is vastly different and better than our first run with the cheaper incubator.
Interesting thing is that with this incubator we set it to the desired temperature, but we also had thermometer/agrometer...

Alright, our Egg of Concern, #4, has shown us her beak, so she can get air. And we've seen at least one other beak. This is earlier than we'd figured so the quiet eggs aren't yet a concern. We saw movement in all of them before lockdown.
We needed to mark the airholes earlier - we can't find the airhole on the egg that's most active. One break on the outside, and since we hear her chirping, we're hoping that means she got her airhole and that the break on the outside of the shell means she can get new air. But we're a bit nervous.
One minichicken decided not to wait for us to wake up. More eggs are rocking and occasionally peeping.
It's hella hard to get out of that egg, so you have to sleep a bunch:
Ah, the "definition of zipping and pipping?" post suggests she IS internally pipping. So if I thought I heard something in the afternoon, that means we'll want to probably do a safety air hole around noon or just a bit after. But I'd very much like to hear back from folks in here before we take...
We've got six eggs in our new incubator, and funny enough, the one egg we were unsure about right along has peeped at us tonight. Four or five good peeps in a row, and we see the egg shaking a little from time to time. I thought I heard singular peeps earlier, but tonight my daughter ran down...
