Day 4 veins

[enggass]

Is it normal to see veining around edge of air sac and not much more on day 4 ? Having trouble seeing embryo... just slight veins near edge of air sac.

I'm just hatching some bantam wyandottes and that's all I saw on a lot of the 25 eggs I have inside. They're on day 15 now and they look fine. I guess it's just about the starting position of the embryo...
