I have a female who has been laying infertile eggs all season long that look very similar to what you are describing. Usually within about a week the eggs begin to turn yellow, and if you candle them it looks like the egg is empty. With good eggs you will see a "ring" of blood vessels where the embryo begins to develope. If you are unsure, just let them incubate until they fungus, collapse, or rot. I've read plenty of stories of odd and discolored eggs that went past the estimated hatching date that still hatched. That's why I don't chuck em till I'm 100% sure there isn't anything going on in them.
Good luck with them!
