My eggs are on day 17. I candled last night and can see movement/veining still in most of them. 2 were iffy. Half the egg (lengthwise, up and down) and showing clear, but then dark mass on the other side. I'm not sure if i saw movement or if my eyes were playing tricks on me. I could also see some sort of liquid moving when i tilted it side to side. How do I tell if a day 17 egg is a quitter? Or, should I just leave it in the bator and hope for the best. It doesn't smell.
