I am going to leave them until I know for sure but mine are alot smaller, the dark spot look the size of a normal egg yolk. I don't know I am going to candle a regular egg, get a different flashlight, and see where I am at after that. Thanks for all the help.
Okay not so confident now, after watching videos on youtube. My dark spot on some are just yolk sized and so of them in the shots were huge compared to mine. BUT I thought I saw some veins in a couple but I don't know now.
