Bator day 14 - 6 eggs - hatching in carton question

[kwack]

I wish it was day 28 already!
I read a few post that talk about better hatch rates when hatching in an egg carton. Most of the posts were chook related and got pretty heated. Just wondering what you duck pros are doing and what your experiences have been. Photos would be much appreciated.

I'm assuming the pulp cartons would be used rather than foam...?
Are they trimmed down at all?
Holes in the bottoms?
Egg position would be...? perfectly upright (aircell)? Side-tilted?

Some of my air cells are wonky shaped, they dip on two sides. Is that normal?

Thanks,

Im using it right now on my wood duck eggs and I had 1 infertile but the other 14 are all developing perfectly. I used foam/styrofoam kind, because I figured it would mess with humidity less than the cardboard kind absorbing some of it. I cut a lot of holes by poking with one end of the scissors around the place for the egg and especially in the bottom. Im waiting till day 10 to check my Aussie Spotteds and Sebbie eggs, but I can update on them Sunday. I put them basically upright and tilt to carton side to side by using a spool of thread and then push the eggs side to side as much as they tilt before the carton stops them.
ETA: Oh, and I cut the top off the carton
