I'm so sorry to be asking a question on incubation that's been so thoroughly covered in multiple posts. Which I've read to the point of complete confusion.
So, it's my first time incubating. Someone gave me 9 Beilefelder eggs and I didn't have a broody to stick them under so I ran to TSC and bought the Farm Innovator 4200 Pro with forced air and egg turner. Stored the eggs (correctly) and spent 24 hours adjusting temp/humidity
Bought 2 digital thermometers (Aviagen and IncuTherm). Negelcted to calibrate so I guessed somewhere between the two because they were so close. So first first 18 days it stayed fairly steady at humidity of 25% and temp of 99-101. So no problem.
Candled at days 7, 10, 14, and then last night at 18. I suck at candling - always have - but I knew that, last night, I had 8 eggs that were fully dark with just a decent size air cell. No, I didn't mark air cell levels at each candling, either. Should have - learned that after the fact.
Nonetheless, 8 "good" eggs candled, took out turner, laid on their side on wire grate. Added a sponge and watched/adjusted humidity til 2am (about 3 hours).
Had a sponge first but couldn't get it up about 50ish. So added a bit of hot water with syringe through air vent (yes, I took out plugs). Then it spiked to 75-80% and I couldn't get it down. Quickly took out the eggs, shook the water out of 'bator, then re-added eggs.
Stayed over 70%.
Checked weather and saw our humidity (Tennessee) was 80%. So I didn't add any water. Then I put the sponge back in. Still high. Went to sleep.
Got up this morning and temp was at 97 and humidity at an alarming 25%!
This has been a real booger, quite honestly, and I'm a wreck. To go 18 days feeling fairly good then to this...
I sure could use some advice. Believe me, I have voraciously combed through this forums for over two weeks on a feeding frenzy of information, and the info is so widely varied that I've tried to just go with the median of all numerical advice.
But did I kill my babies overnight?
Sorry it's so long - I tend to over-explain. :p
Oh, I did read the Hatching 101 page, too.

Nope, they should be okay. Keep the humidity up now.

Post pics of the chicks!
 
Id get the humidity back to where it needs to be and just let the eggs be. Good luck and keep us posted
 
Thanks to you both. I've held steady at 65% humidity and 99 degrees all day. We'll see, I guess. Will post pics...if I have babies. :)
