I never knew that about the calls @RavynFallen Thats actually pretty interesting.
I personally think chicken eggs do better lying down, too. Not that they necessarily need to be laid down to have a successful hatch, i just find that its easier....I've had more success with eggs laying down..rather than upright, i dont incubate upright. I guess its because the natural way is laying down, for the eggs.
Exactly right... all eggs really do better incubating on their sides... just some that are drastically different...
Call ducks are notoriously difficult to hatch though... I've ran 2 dozen eggs in a regular upright turner, was lucky to get 4 to 6 hatched and thriving... laying them down, hand turning them, and a few days misting them, I got 24 out of 26 to hatch and thrive... they are a difficult breed to hatch, but extremely rewarding...
