Finding imperfections in eggs

[horsewishr]

Most of my eggs are perfect. But I did have one with a meat spot, and yesterday I found one with a gray area around the chalaza. Both eggs were very fresh.

My question is this: is there a way to find these imperfections before I crack the egg open? It's not a big deal to me, but I want to make sure the eggs I give away are perfect. How do commercial egg operations only sell perfect eggs?

you can candle them just as if you are candling a egg to see if it is fertal and you will see a dark spot if there is a meat spot or blood spot.

what causes the meat spot or blood spot? Does it effect the egg and if you should eat it? Sorry, last question...Is it something the average person (not a "chicken person") would even notice? I guess today I am an inquiring mind..
