Learning again. Didn't know what candling was but now I do! Sounds like the newer high powered LED flashlights have replaced the old candle light method?
I also learned that you have to turn your duck eggs 180 degrees 4-5 times a day or the embryo will not form properly?? Someone has to stay home and turn the eggs in the incubator? Amazing!

Thanks for the update and the work to try to keep more wood ducks in the wild.

Sadly no wood ducks showed up this morning!
