How often do you candle your duck eggs?

[maus]

I candled mine at 7 days and now at 14. When should I do it again or should I just leave them be until the 25th day? And wow do the air cells look weird on shipped eggs!

Mine weren't shipped and I was 3 for 3!!! My last one hatched just this morning. I candle often and these guys were both at 31 days, so be patient. They are mutts, their dad was a Rouen and their moms were Rouen/Swedish mixes. The ducklings are all black with gold on their chests, gold stripes on their eyes and they all have 6 gold dots on their backs. The last one from this morning, and the smallest by far had an all gold head and neck, wonder if that's the boy. It's feet and beak also have alot of pink in them, where the other 2 are solid black beaks, feet and legs.
Good luck, I found them the easiest eggs to hatch to date. Temps were all over the place, crazy out of control temps and they were the lone survivors with a handful of silkies.
