geese dont guard anything, they are all bluff and will be a meal for predators too. guinea are alarm systems only. A secure house they are closed in at night is the only way to protect them fully.I'd like to get my Muscovy set up in the back yard near the pond, but I'm worried about predators getting to them. Any thoughts on adding another bird to the little flock as a guardian? Goose (breed?), guinea, ??
