Question about large eggs

[tberggren]

I am on day 15 and have one egg that is larger than the others and at first glance you'd toss it as a clear. BUT I swear deep inside the egg I see some movement. Could my eyes just be playing tricks on me or if it was viable would there be dark obvious veining no matter what the size of the egg??

put a ? mark on it and candle it later but it should be nomatter what size
