Sorry about Mama Jean, but she was so ready to go.
On the hatching thing I may can help:

This tells about soaking the eggs in Vitamin C for 2 minutes and letting dry before you put in 'bator. Then on day 16 do a cool down phase for 6 hrs. Take top off and spritz. Then after 6 hrs the temp will be around 75 degrees put top back on. Good results
HOWEVER, Ron Ott said he doesn't know anything about the Vitamin C soak and what he does is from day 8 to day 18 he takes the top off and spritzes water and lets them sit for 2 hrs. Hatchability and vitality rate is way up. This is the method I'm doing for my White Plymouth Rocks. I'm on day 20 I think and am on lockdown. We'll see. I've tried to do everything like he said and he has a 90 something hatch rate. I do a dry hatch method. I've got Swedish Flower Hen eggs coming next week and I think I'll try the Vitamin C soak and then do Rons way. Out the the rocks I have now I have 2 clears and 11 that are growing. That is all I know.
Edited: With our humidity, don't spritz
