Thanks. I did read your information before I asked. Each air cell has varying degrees of wiggle-roll. I only labeled 6 as "rolly" but some of those had a small spot that may have been attached so I didn't move them around too much. 6 were "wiggly". 3 were "?" because I didn't see a clear AC. Knowing that wiggly is ok I'm feeling better about this hatch. I still won't turn them at all today. I'll tip them gently tomorrow. I wasn't sure about the hatchability of rolly ones. The two eggs I kept in the incubator from Feb set are rolly and I think the embryos may have died recently. They're on Day 14 today and last night looked only day 10 size. Veins disappeared too. I will probably take them out today.
