I searched here on BYC and didn't find anything about this. I had a hen (or three) laying under my shed; there were 13 eggs by the time I found them. I washed them and put them in the fridge and am checking each one before I use it (by cracking it into a separate bowl). Anyway, two of them so far have had the yolk sticking to the inside of the shells!!! What is that? Why does it happen? Is there any way that I can prevent it? (I'm guessing the answer to this is not to leave them sit under the shed for two weeks. lol) Are they safe to eat?
