Eggs developing spots once in fridge??

Hi everyone!! I have google searched this and didn't find anything to match what I'm saying, so decided to start this.

My Black Star started laying about two weeks or so ago. At first she laid shell-less eggs, then started laying normal after the first week. The first shelled egg she laid was splattered with liquid (what I assumed to be poop??).. The egg was GIGANTIC, so I assumed that caused the misfire. Next day, same thing.. GIANT egg, although not quite as dirty.

Today I went to put up my eggs for the day and noticed that her egg from yesterday, which was perfectly clean when I put it in the carton, now has what appears to be the same "stuff" on it. Only this time I know it's not fecal matter because like I said it was clean when I took it from the nest box.

Here is a picture to show what I mean:



I almost cracked it before I posted this, but decided to wait and see if anyone has any ideas?? Hate to waste it if anyone comes up with an explanation.. these things are hard earned! LOL.

I can scrape off the stuff with my fingernail though it's not easy. I've seen eggs in a bator do this but not in the fridge. This egg was room temp by the time I got it from the nest box so it's not like it was just-laid-hot when it went in the fridge.

Anyone?

Also, for good measure, here's the full pic of my first full dozen fresh eggs. Currently I have a BO and my Black Star laying. You can see one of the BIG ones the poor dear laid as well, lol. The carton will hardly close over it.

 

Thanks! Yes, I guess I'll just judge for myself when I do go to use it.. I can say, what I've used so far they are NICE! The whites so nice and firm, you can almost stick the fork through them & pick them up! Nothing like store eggs at all.

 

Thank you VERY much, everyone! I did end up using the spotty egg(s) this weekend and I lived to tell about it! I'm so glad there is an explanation.. Thanks dandrews!!

Gardner- I don't really have a set time. Sometimes I end up getting the egg as soon as it's laid, sometimes it's sat all day until o get home. Either way it's straight to the fridge for mine. Unless I sit them down and forget, in which case it's when I remember to.
