I got my geese to protect my ducks during the day when they are out. Seems to be working for me. I have good fencing but living in the country with the feral cats, neighbors dogs, and a ton of other wildlife I like the fact that the geese make a big row when there is something. I also have the goose pen and duck pen right under my window so if anything does happen at night I will hear it and be able to respond. Its taken time to train him but my gander is able to usually keep keep quiet unless something is wrong. Knowing he is quiet gives me peace of mind.
