Hi,I hatch lots of geese and duck eggs,I would sagest you set your humidity to 45-50%,I always like to turn duck and goose eggs buy hand as I have far higher hatch rates buy doing so,I think your average small incy is designed to turn a small egg from a chicken not a large egg such as a goose.I turn the eggs 3 times a day end over end only don't rotate them as you can wind up the elasticy bits that hold the yolk in place.When I turn the eggs I then spray them with luke warm water until it runs off them.
As soon as the eggs start to pip,stop turning them and raise the humidity as high as you get it at least 70%.
Below is a picture of the best hatch I ever had from my octagon 20, 9 from 9 goose eggs.In the picture I have all ready removed the shells it was so tight in there at first I thought they were dead.I am in canterbury so not far from you either.
Graham.
