This! Most of my birds free range, but they stick to my property. They don't go to the neighbors, they don't wander into the road or the bordering pastures, they stay where they belong!
Muscovies particularly. They have a trilling gobble sound, not an obnoxious quack. I can't hear mine until I get like 40 feet away when they're excited
That comparison is so true. Our neighbor had a pair and even a mild away, we heard them clearly. To make it worse, we are in a valley, so they echoed. They would reply to their own echo for hours
If you cannot keep your birds from wandering off your property, you need to pen them securely. Otherwise you're just as bad as the people who let their dogs and cats wander
