The eggs are a pinkish color. About 24 hours before hatching they get a blueish white mold appearance to them, which is the eggs becoming thinner as they are about to hatch. They don't actually turn blue, its more of a moldy appearance. If the clutches are left where they are laid, its very very common for the outer eggs to dry out too much and prevent any of hte clutch from hatching. I incubate mine. Once I am on my feet again, I am going to do a post on my hatching method. There is one stickied at the top that can be used as well. Female bridgesii do lay eggs regardless of fertilization as part of their normal reproductive health.
