Ducks and Geese

[JJpuck]

Hi all. I was wondering if it is possible to raise and keep ducks and geese together. Will the size and social differences be too much for the ducks and geese to handle and they will not get along?

If it helps I am considering two Sebastopol geese, along with a Black Swedish and a Welsh Harlequin.
