We have used our Brinsea Octagon for both hens and goose eggs, some years more successfully than others. I have done both automatic and manual egg turning for goose eggs. It isn't the actual turning that makes a difference, but the moisture. More recently we had some spectacular failures with dead-in-the-shell goslings, they drowned. Even though I ran the incubator on 30% (as in no water added during incubation) weighed (and there were signiifcant differences of water loss in the same hatch) etc etc - we have now given up on geese (that said the last year our goose wasn't successful either, as the boy must have been shooting blanks, all eggs were infertile...).
Goose eggs are tricky...
