Eggs fell out of incubator. How to tell not viable?

[Donna Jeanne]

Great news to share. I candled the eggs tonight and they are all living and growing!!! The eggs no longer have the U-shape disconnect. The air sacs are a bit bigger than I’d like so I increased the humidity so my fingers are crossed that they’ll continue to grow and eventually hatch. Thank you for all your assistance and advice. I’m amazed that they’re doing well!
