We have a flock of Khakis for eggs. They have an enclosure that gets muddy in the spring after all of the heavy rain. Then it greens up and is self managed. The ducks free range in the rest of the yard during most daylight hours. They have not destroyed the yard by any means - they will attack the strawberries or tomatoes if they get a chance so fencing some of the garden becomes necessary during certain phases. They don't produce anymore mucking work in their night run than my brothers chickens do for him. As for noise - they let me know when they want out in the morning or if they think they need feeding or something. Other than that, they are pretty quiet. It is more likely to hear a neighbors dog barking than the ducks. We have a small pond in their pen - 7' diameter and 1 kiddie pool we move around in the warmer months in the yard so they can keep their feathers clean. Our neighbors hear them on occasion and are not bothered by them - granted we are the small lot in the 'neighborhood' out in farm country. We tend to keep 5-6 hens and it keeps 3-4 households in fresh eggs most of the year plus some, not to mention the slug,fly, mosquito, spider control we get out them. We have the best of both with my brother having the chickens and only living a few miles away. What ever you decide, good luck with it!
