When you say floating do you mean if you were to lay it on it's side and roll the egg, the air cell would follow you? it would look like a bubble? this is called deatached air cell. Or do you mean if you lay the egg on it's side it stays at the larger end but you can see if moving around, doesn't go past the top, just moves around at the top? this is called loose air cell..Forgive me if this has been asked and answered (probably a dozen times). I did try to search the thread but I must not be using the exact, perfect keywords. The eggs I have in the incubator were all shipped. In almost every one of the 27 eggs, the air cells were floating all over in them, which I expected. So they sat for a time, then they were checked again. AS FAR AS I CAN TELL, most of them seemed to be stable. I think I counted 11 that were still very wobbly - I'll have to recheck my notes. Anyway, when they went into the incubators I put them all with the pointy end down, fat end up, because of the air cells. Now, Blooie's stoopid question of the day - (and I'm sure will be many more) I see that most people incubate and hatch with the eggs on their sides. Is there at time in this process that I should shift mine to that position, or should I leave them the whole time? I dunno - I'm wingin' it here!!
