Crossing the Road
I see what you mean about the air cells! Yes keeping point down is commonly done in the case of bad air cells, and some turners have them this way- it wong harm them at all. Though you are supposed to tilt them, in place of turning them. Especially for the younger ones.PHOTOS ADDED. It's hard to do it at the same time as candling since the eggs are at 20 days now. Some are only at 14 days though.
What about keeping them up and down? the point is down and blunt side up. Is that dangerous for hatching and incubating?
When it comes to hatching, in lockdown, Im not sure if you should keep them point down or lie on their sides, so someone else would advise better on that note. But its fine to have them stood up during incubation-dont worry!
