Let them settle at normal room temp, 70-75F, if you'll be placing them in the bator within a day or two. This gives time for any air bubbles to re-absorb/dissipate. You DON'T need to turn them or tilt them during this time. They do need to be in a carton, big end (air cell end) up.
Yes, you can candle to find the air cell. In a darkened room, shine your candling light (I use a 9 LED flashlight) sideways through the end of the egg. The air cell will show as a slightly darker or lighter (depending on the color of the shell) circular area. In a fresh egg, it won't be very big. And they can be hard to see. It took me forever to figure out how to see them.
You won't see a bull's eye on the yolk when candling, unless you have really thin light colored shells, and a really bright light, and then, only maybe.
If your air cells are detached/ruptured, letting them rest is unlikely to do anything about that, but many people have managed to hatch eggs with damaged air cells. They use cartons, so the air cell remains at the top of the egg, and tilt the cartons rather than doing a wider turning of the eggs. The purpose of turning/tilting the eggs is to prevent the embryo from sticking to the shell. Gentle tilting of the egg 3 times a day is enough to do this. A ruptured membrane inside the egg can't "heal" or "repair itself". However, as the egg develops, and some of the moisture evaporates from the egg, air space can develop where a normal air cell should have been.
If the air cells are ruptured, you'll see a free floating bubble in the egg, it will move easily to which ever side of the egg is up. This is what people call a "detached air cell", but really, it's the bubble of air that was between the membrane layers. When the inner membrane ruptures, the air escapes into the egg white. When the eggs rest, upright, it's possible that the layers of membrane may pull apart, and the air re-enter the small cavity. It gives the impression of "re-attaching". If the eggs are tilted or turned, it could interfere in this process.
Sometimes, air cells are damaged, but not ruptured. These can look elongated, or somewhat splattered, giving them an irregular amoeba-like shape. Many people have successfully hatched eggs like this, too.
Good luck, I hope your air cells are all intact, and you have a great hatch!
