I've several living and thriving birds from both refridgerated 42 degrees and near frozen (found in unheated coop at around 34 degrees) eggs.
Science rarely asks nature it's opinion and nature often thumbs it's nose at science.
Chicks or ducks that die two weeks after hatch probably died of MG or coccidia.
While the odds are better if you don't, the odds are roughly the same as well shipped eggs. If it's all ya got, go for it.
I hatched 7/11 chilled, wet, muddy, unturned, filthy turkey eggs. Eggs no scientific or poultry article ever even suggested would hatch. They're now five week olds and thriving, okay and adorable and momma's babies.
If you've got the time and will to defy the odds. Go for it.
