I agree with @CluckNDoodle. I would leave it for a couple of days and see to ensure but, yes, they’re likely both quitters. Sometimes depending on when it happened and the position the embryo was forming in, the ring doesn’t go all the way around.So far Of the 12 eggs I set 10 days ago 4 were duds. One has a saddle cell and tonight I see this. Not being super experienced I will leave them in and keep checking unless someone confirms my feeling that I’m looking at bloodlines. It’s not all the way round in a circle, just one side
Also, sometimes veins look that thick or almost stuck in a spot that make you question the viability of a healthy egg, but that doesn’t usually happen until day 14 and later.
