Crowing
I had a power outage when my eggs were on day 17 and they got down to 55° because I had a fan going in there (that’s another story) and I had half a bit over half still hatch. There was no power for 6 hours before I could move it to another place to plug in. I’m gonna guess your chicks will be fine if you wrap them in a blanket (but leave some room for air) and place some hand warmers in there!
