I think I know what I’m looking at here, but I would like confirmation or otherwise from more experienced eyes. This egg is dead, yes? Did it get too hot? I have never candled white eggs before this. I candled last night, day 11, and saw a peculiar pattern. I rotate my eggs by row and also by egg within the row. In two rows, four or five eggs in the center look like this. I have never seen such a dark mass when candling before unless it was a nearly hatched chick taking up all the space. I know the incubator spiked, I walked in to find it happening. I have to keep the temp high to compensate for a flawed thermometer, but it probably got up to 102, though only near the heat element and not throughout the incubator. The pattern of eggs with this dark mass makes it look like those two rows, which are beside one another, were directly under the heat during the spike. The eggs on the ends of the rows stayed cool enough, as did all the other rows, but it killed these eggs. What do you think? These ones are gone and I should remove them, yes?

I'm not sure that egg is dead. I can't see a clear blood ring that goes all around. What day is it on? Can you get a pic with the light shining through the pointed end of the egg? Sometimes in dead eggs it is easier to see the bloodring.
 
It sadly looks dead to me. Usually, you can see obvious blood vessels running up to the air cell, and when the embryo dies the vessels deteriorate rapidly. It may just be the image, but i do not see any blood vessels. I hope I am wrong and they are alive!:fl
 
The above picture is the light shining through the pointy end of the egg.

These shots are from just now, the morning of day 12.

Here’s one I think looks good. Also white. I can see blood vessels in the first picture and the embryo is shady, not super dark like the others.

That embryo is alive! it looks very healthy. :D
 
I'm going to say that all the photos show live embryos but I suppose the only way to be sure is put them back and candle again after another 24 hours. You should be able to see more clearly any forming blood rings in dead ones. The 102 temperature spike isn't that high to definitely have killed the hotter eggs.
