I have two geese now, but I used to have three and when they danced in a circle around my dog flapping and screaming and nipping at her I decided to keep my dog separate
Geese make wonderful additions to a homestead they are loud and watchful, so they "sound the alarm" when danger is near, but they wont fight off predators to save your chickens.
I love my geese as pets, but they are loud, and dont get along with my ducks and chickens, so I keep my geese...
