Was just writing a PM back but any advice would be welcome!!
I read on this forum to incubate shipped eggs w/o turning for the first week to allow air cells to heal. I can't find the thread - but it was a long one, I thought I'd give it a try with the project eggs to give them the best chance. I would love to give it another shot though and try turning them from day 1. Or I'll be left wondering if it was the shipping or the lack of turning that caused so many to quit! When I candled them before putting them in the incubator they didn't look too bad, I only saw a few with air cells floating around, but when I candled after a week, it was clearer that a lot of the air cells were detached

Some seemed to heal but still had the air cell running down the sides - others were still floating around loose.
My temps were good, within .5 degrees of 99.5 the whole time, I started out with humidity low (around 30%) but when I candled at a week some of the air cells looked HUGE so I did increase humidity and tried to keep it around 40-45%.
A lot of the eggs quit by day 7 - one I cracked open had a crossed beak and quit at about day 18ish, the other (4?) eggs that were in lockdown are still in my bator, today was day 26, I wanted to give them that long just in case, but don't know if I have the heart to crack them open. Maybe I will get my husband to do it...
I hope I'm not forgetting anything...but would love some input from others who have hatched these eggs!
I managed to find the thread about not turning shipped eggs...
