I have just two - a bonded pair. They were raised with our chickens and live with them. The only time they make noise is when they see a hawk or a predator and maybe when someone they don’t recognize. They do peep to each other to keep track of each other. I absolutely love them. I love that they are the guardians of my hens. They literally do a sweep of the yard at night to make sure everyone is in the coop before going in themselves. They are worth their weight in gold to me.
