I don't see any veins, at 15 days they should still be clearly visible. is it just not picking up in the camera or are there no veins. also at 15 days when you candle them they wiggle all over the place...is it moving? or when you turn the egg does it more like slosh from one side to the other..with out veins i'd say it was a fetus but it is not alive anymore but i don't want to be hasty until you can tell me the answers to the questions to say for sure.
