I did my eggtopsies.
One of the 4 had definitely quit earlier -- it was the one I thought dubious but had *thought* I'd seen it move. So not very surprising.
2 pipped externally but didn't absorb their yolks.
The egg with the wonky air cell had pipped internally -- into the air cell -- but didn't absorb it's yolk.
I couldn't see any obvious deformities or malpositions so I have no idea what happened.
