Thank you! My incubator has been running a touch colder than 99.5, so I’m actually expecting them a little late. Last time, before I found this site, I followed the incubators “instructions” and topped up all the water channels for lockdown. My humidity jumped up to 70% then as soon as my first chick hatched, the paper towels I had lined it with wicked up water and I was at 89-100% humidity, it didn’t go well from there at all and I had a 27% hatch rate with all but 3 eggs very late stage quitters.Most go to lockdown at 18 days. But it depends on the development of course, if they're late 19 is ok. I'd recommend not adding water until they've externally pipped. Extra water during hatch is mostly about keeping the inside of the egg moist while after the shell is broken.
I’m a little anxious this time, and these are my first farm collected eggs
Sire is my assisted hatch from that first sad experience, and Mama’s are some hy-line reds and a Columbia rock, mostly. I also have 8 decent looking Marans eggs but mama is a little young, so I’m anxious about that as well.

and I had committed to a 7pm-bedtime candling appointment with an excited 7 year old. It took me almost 7 months to muster the courage (and more stable room temperatures) to try hatching again.
