Mine are getting crotchety and I just moved them into their own pen today.
Usually they do fine with the other birds, but during breeding season they get a bit cranky, lol.
You need to add two geese. Geese need to have a friend of their own kind. Ducks are not the same as another goose. Two females is fine if you don't want a gander.
I personally have Tufted Romans, and they are great little geese. Excellent temperaments, very friendly. I definitely recommend them.
