I have brown eggs, and for the life of me can never find veining! Considering I have four live chick's (momma did the work!) I have beeb incubating but not had any luck seeing developement. I can see when they are clear, and I can see the dark shadow, but how do I know if it's rotten or not? I had two I thought were bad, and cracked them to find chicks inside. Help!!
