Am I the only one having a really rough time candling brown eggs? Some I can't even get a light to penitrate the shell. Cyn, says to see the veins, what veins, these eggs are speckled and can't define anything. I've seen some black spots come to the top on some. And I think I have more good ones than I might have thought, but what if they are bad ones with blood spots. Am I not doing this right or something?
