I always use my turner because I'm not able to hand turn often enough. With shipped eggs, I usually sit it in the turner, i just don't plug the turner in for a day or two, depending on how bad the air cells look. Hopefully your eggs won't be too bad.
I have 2 Octagon 20s. One has a pump, the other doesn't. I tried something new a couple of weeks ago with the non-pump one. Used a piece of quilt batting (the thin cotton inner layer) thru the wells for extra humidity. Worked well!
Hope your eggs arrive in great condition. I have more on the way also.
Do you place shipped eggs on their sides for the hatch? What kind of hatch rates are you getting? I was really worried about using the turner with damaged cells. Maybe I'm worrying too much?
The batting cloth is a great idea. My go-to method is the Viva paper towel. Seems to hold a lot more water (than regular towels) and regulates well. Easy to tear into smaller pieces when necessary.
