I candled the eggs that people had named:
3: looks dark except an air pocket at the bottom - large cracks at the top (big end)
7: looks empty except a large blood ring
9: completely empty
14: completely dark
19: mostly light with a small dark area, possible blood ring?
20: mostly light with a larger dark area, possible blood ring?
Sorry guys, not looking very good. I'll candle some more later to see if I can find some better looking ones, and you can pick different eggs.
I randomly candled a couple when my Incu-bright first arrived and saw some veins but didn't write down which ones they were.
