I would say give it a try. My 2 ChineseXEmden ganders adopted chicks and still cared for them until they were grown and then I got them some African goslings. They love the babies and geese are so family oriented that I see no reason why ducklings wouldn't work. The way geese act always amazes me........PopI do have a question, I have three toulouse geese. One in one pen and 2 in another, they all are in with ducks. I just hatched out 11 ducklings and would the geese adopt the ducklings? I think I have 2 ganders and 1 goose and they are molting purtty heavy right now. Should I give a try? Please help as I really don't want to brood inside the barn again. The ducklings will be a week old on the 13th.
