I candled tonight at day 3 (I know it's early but . . . ) I see the air sac area and then I see dark blobs with no veining at the top end in the air sac area. Are my eggs developing or is that the yolk sac I am seeing? These eggs came from MT and I am in FL and they were not cracked in shipment but not sure they weren't scrambled in the process. One egg I can see the dark mass move up and down depending on whether at small or large end of egg. The other ones the masses stay in he upper end whether turning large or small end. I've looked at bazillion pics but not sure if it is yolk or development I am seeing. Thanks!
