What is on this egg???

[Chick Charm]

It is a bad egg. It is actually leaking or seeping from the inside. IT WILL STINK if you break it. Don't throw it away in the house. TRUST ME. It happens, no big deal. BUT OH THAT SMELL!

If the spots can be wiped off, it may just be residual yolk from another egg that got broken in the nest. Does the egg smell? If it is leaking, it would surely smell.

Aren't there some more pictures in this forum somewhere that show more eggs that are about ready to explode?
How long from when you see the "stuff" on the egg to when it explodes? I think I have one that has some white patches...I won't be home for another 10 hrs... they have been in the bator 4 days,,Is that too early to worry about exploding? They had been setting out for about 1 week waiting to accumulate enough...
