Blood spots in eggs?

[Rivka]

We keep kosher at our house. Blood spots in eggs as I have been taught make the egg unkosher. I would rather give these eggs to our friends who are not kosher or jewish and don't care about this. Is there a method at home to tell if blood spot is in egg before cracking? Thanks

Every once in a while I get a little blood spot. I have never heard of a way to tell ahead of time if there is one in an egg.

The commercial egg farms do large scale candling to check for blood and meat spots, but I don't imagine that would be practical at home.
A blood spot simply means a blood vessel ruptured during the formation of the yolk. Here's more info. on blood spots:
