i don't have experience with goose eggs. but last year i put duck eggs in it and it worked out just fine. i had to separate a few of them cuz some were kinda big. but goose eggs, i don't know, i'd be afraid they may perhaps fall out or something? good question though.
Goose eggs will do best laid on their side and turned a full half turn three or more times a day. There is a goose egg arangement for the yellow Hovabator turner that spaces out the turning rails and has hardware cloth baskets to hold the eggs. This is something a handy person could duplicate quite easily. I would still mark the eggs with an X and an O and give them a half turn once a day as the turner just rocks them back and forth.
