    My great-aunt was talking chickens with me recently, and said a couple of things I hadn't heard before. So I've been doing some research online, and can't find anything to support what she said. So now I'm wondering if it's a wive's tale. Here's the scoop:

    1) If there's a white spot in the yolk: It's been fertilized. Good to eat.

    2) If there's a brown spot in the yolk: It's a meat spot. Good to eat or can fish it out.

    3) ***If there's a black spot in the yolk: It's a parasite. Not good to eat. Fish it out or throw out the whole egg.***

    Scenario #3 is the one I'm wondering about. What do you think? Is there any truth to that?

    I'm not sure about #3, but #1 isn't entirely true, at least. Even eggs that aren't fertilized have a white spot.

    I've never seen a black spot in the yolk, so I can't say. Agree with Pyxis on white spots. That does not necessarily indicate a fertilized egg. Meat spots yes - eat or fish out, whatever your preference.

    I did find a black spot in the very first egg my Red Ranger laid a week ago. Had no clue what it was. But I picked it out and cooked and ate the egg anyway. I'm not sick. Not yet anyway[​IMG][​IMG]

    Every day of the week it used to be my chore to candle the eggs that our hens laid. Every day there was anywhere between 400 to 500 dozen. Because all these eggs were produced by caged hens there were never any parasites present in any of the eggs that went to the grocery store shelves or that we sold on the farm, or inside any of the reject eggs that we ate ourselves. In fact we had enough reject eggs that my boyhood friends and myself used to have raw egg battles in the woods. While using reject eggs in the kitchen my mom always broke out all the eggs in a tea cup and scooped out any spots with a spoon or table knife. When I left commercial poultry keeping behind and started raising game fowl in free range conditions I never again candled another fresh egg but I always break out all free range eggs that I or my wife cook with. Over several decades I only remember finding a couple of worms in these free range eggs but they didn't originate there. They most likely took a wrong turn in the hens reproductive system and ended up being incorporated in the egg while the egg was still in the shell gland. I was confident enough in the purity of our commercial eggs that I ate raw eggs on occasion by breaking off the pointed end and sucking the contents out, much like an egg sucking varmint. The trick is in choosing a smoking hot fresh egg. Hey, Ben & Jerry or ice cream factories as far as I know still use raw eggs in their final product. These eggs may be coddled or maybe they're not.
