I waited another week & still saw no growth. By then the good eggs were easy to tell. When I cracked the bad eggs open, some had dead rotting embryos, others nothing but the ring grew.
Don't rush to throw out, though. An early vein & blood ring could look alike. When all the other good eggs have spidery veins & you can see the chick's eye looking back, you'll know there's a problem with a mostly clear egg. I waited until the embryo shadow was fairly large in the healthy eggs.
