This is my first go. Someone in another group I am in suggested the method I am using so I am following it verbatim. If I don't have success I will definitely try something different. I think the cooling and misting is to mimic the hen getting off the nest and returning from a dip. I was curious about turning over the pointy end. I though a horizontal rotation would be used but I'll try it his way and see how it goes.
Yes, the cooling and misting is closest to natural. I'm just not sure about the rotation. I'll be curious to see how it goes for you. I'm not discouraging it... it could work great!
This is from Storey's Guide to Raising Ducks. They do say they have increased results with misting. I think I did it with my very first duck hatch (Swedish), but not after that. I needed to mist one set of Call eggs once, just to increase moisture loss. I may consider doing it with this hatch.
