I found a quail nest and then the mom got smoked...

Well if you see shadows moving, the eggs have probably been incubated at least 15 or so days. The only thing that could really keep them from hatching is little to no humidity. As for the air cell, the size varies. Being such a small egg, it may be hard to see the air cell...especially if they have lots of spots.

Good luck!!
