So Ive been incubating 6 turkey eggs in a Styrofoam type incubator with an auto turner, it rocks them vertically. Everything looked normal. I moved them to a mini eco advanced and laid them on their sides for hand turning. I turned 3x a day, X rolls to the right and O roll back to the left. I candled them all today for lockdown, most had saddle shaped air cells that take up a little under half of the egg. What happened, what would causes perfect air cells to suddenly morph? What do I need to worry about?
