Egg question

SO I was looking at my eggs today and they seem to be crack all around the with vertical lines. if the egg was to stand like an egg. both of them are doing it but one more then the other, any ideas what this could be? couldnt get a pic camera wouldnt focus in macro.

I think that's normal, all my eggs have those vertical lines and they grow more prominent as the egg swells to allow the fetus more room to grow.

Yeah, some eggs get the vertical lines and some don't. As long as it is not an actual crack that is leaking fluid it's usually just something like a stretch mark.

ok cool wanted to make sure, it kinda scared me.
