Good to know! We can't keep geese where we live, but someone else had mentioned it to me. Apparently he had greater success. Sorry about your rooster :-(I’ll speak about guard geese and maybe it’s just mine but when a predator comes around my geese do not make any noise and are just as terrified as the chickens and ducks. We had a hawk swoop in and kill one of our Bantam roosters a few weeks ago and not one sound was made and when I came outside to check everyone I knew something wasn’t right everyone was hiding out. Now if we drive up or anyone else our geese sound off. About all they are is bluff when it comes to predators.
