30% during incubation? Isn't that a bit low? And this is for call ducks, yes? Sorry for the rapid-fire questions, I can't get hold of the breeder otherwise I'd get my info straight from the horse's mouth.
No that is perfect. Follow clousert's directions to the T and I promise you will have a better hatch, we've tweaked around with it and these produce the best hatch rates for several of us.
I just got done trying to hatch upright, definitely lowered my hatch rate.
The humidity is good at 30%, main problem with calls and incubation is they fail to absorb their yolk sac, so humidity is crucial.
