I am new to candeling eggs. Today is day 6. I must not have a bright enough light or all my eggs are no good. They are Blach Copper Marans so they are dark shells. There is one for sure that I can see veins in. It seems that they all have a black blob in the top half. I accidently dropped on on the counter...argh...so I broke it open and found what appeared to be a embryo 2 dark spots in it. The yoke seemed to be mixed up and not as it would appear as when you would open them fresh. Anybody have any ideas or imputs? It would be much appreiciated.
