Help! Egg Exploded I Think?

[Soltaria]

I got my eggs in the mail yesterday. Most had detached air sacks and two had cracks in them that I sealed up with candle wax. I got them all set up and kept the two cracked eggs away from all the other ones in case they exploded.
Well one of my eggs that I didn't see any kind of cracks or anything in ended up being the culprit. It didn't do what I would expect from the word "exploded" but I don't know if that's what you would call it or not. It looked like the egg was under pressure and someone pricked a tiny hole in it and gunk poured out and piled up on top. When I picked it up there was a puddle underneath it.
I cleaned everything with vinegar and as best I can tell it didn't get on any of the other eggs. Is there anything else I am supposed to do? Is this an exploded egg?

Anybody?

Probably just a bad egg. The oozing says a tiny hole got poked into the egg and cut the inner membrane.

Exploded would have had egg sprayed all over the inside of the machine. And there would have been a strong sulfur smell if it was spoiled.

Vinegar works well as a wash while the eggs are incubating.
