Assuming you candled day five or day six, the embryos wouldn't have developed enough for their veins to grow through the whole egg. Give them a few days and check again.She's been broody for a week, i checked the eggs this evening and they both have veining and i can see the embryo, I'm just not 100% sure about them, they look a lot different than my first hatch that i incubated. Its like one side has the development and the other side is clear? If that makes sense. The eggs i incubated a few months ago had veining throughout the whole egg.
