Ok so today is day 7 and I candled two eggs out of 13. Candling more tonight. I compared them to the thread with the progression of the eggs troughout each day well one of my eggs you can clearly see has veins. The other one has a black blob towards the blunt end of the egg. Is that one not growing or do they just look different. I didnt see a blood ring just a blob. This confuses me! I know I should just wait but its soooo hard!
