My gosh, I was told that if the eggs got to 106 to figure they were dead! I know sometimes the air outside is hotter than the optimum 100 for hatching but the temp under the hen is what determines the hatch and it probably isn't that hot under her. Of course if she gets off for a while the egg temp would raise.
I belong to a group of rare chicken breeders who are supposed to know what they are doing and they were the ones who told me that 106 was tops. In fact the owner of the list told me if they got to 105 to toss them.
Just goes to show that you can't believe everything someone tells you.
I think you have to thin of the egg as a hollow thing with jelly inside so the chick may be visible all around the egg and sometimes they rotate too as you turn the egg so you could be seeing it every way you turn it instead of just on one side.
