First time duck incubating! Help!

[Katelyn1153]

I just started with khaki duck eggs. I'm on day 5 and they all have a C shape air sac some have a large air sac at one end of the egg. Still non have veins and every where I look online people candle on day 5 and have veins. Could it be that all 18 of mine are dead? Here are 2 of my eggs. All 18 look the same though. Please help!

i never candle until day 10, you can see the veins then. typically i look for dark mass instead of veins, and throw out any bacterial rings.
