@Joanie1975 I'd like to jump in on this old thread as well - more questions than answers, but if we share our experiences, hopefully we'll learn something.
I am in a similar situation - 10 eggs with detached air cells, in the incubator on day 12 today. I also have two more batches being shipped due to arrive tomorrow and will do things differently with these eggs right from the start.
First time with dealing with shipped eggs and it's been a steep learning curve. I didn't catch the detached egg cells until day 7 when I candled. Up until that point, eggs had been flat in the incubator and turned 5 times per day. (After the first week, I turn 3 times a day.)
So, I have the 10 eggs with detached air cells in cardboard egg cartons with the bottoms ripped out for air circulation and I have been moving them VERY GENTLY from side to side and then a quarter clockwise turn 3 x's a day. I plan to candle sometime between day 14 and 16. At day 16 I will stop turning.
I have posted in a couple of different places about laying down vs. keeping upright for hatching and am still trying to read opinions and will make a decision. One posting mentioned leaving upright until the first egg pips and then lay them all down and start lockdown. Still trying to decide what to do....
Anyway, always appreciate ideas and sharing of information. Will keep you posted.
BTW - I read that a 25% hatch rate with detached air cells is a good hatch rate. Gives us a bar to work toward and exceed.
