I am nearing the end of the incubation period for the eggs I currently have going. Last week, I broke open 9 eggs that were obviously clear during candling, with no chick development. When I broke them open, I could not even see a red dot, or anything that looked like they were fertile. Two days ago, I broke an egg that was stinky, and there was a definite something in it (along with disgusting liquid), which leads me to believe it was fertile and/or had an embryo that was a "quitter".
My question is, when the incubation is done, and certain eggs don't hatch, when I break them to see what went on, will there be some indication, even though they will be over 3 weeks old, whether they were fertile or not? If the eggs are just egg looking and I see no red or any other variance, is this indicative of it never having been fertilized to begin with? Were the eggs I broke open (and saw nothing inside) conclusively never fertile, or can the signs disappear within the 21 days of incubation?
