Depends on if your neighbors like the sound of early morning duck quacking or not. The boys they won't hear at all. The girls are another story. Every Mallard derived breed (which is all of them except Muscovies and some wild types/exotics). Some individuals aren't too bad. I had a Black Swedish hen who never was obnoxious. But then I had a Saxony hen and a Pekin/Mallard cross hen that announced themselves early, and when ever they heard the car door, or the house door, or footsteps on the walkway. Those two were extra noisy.
My 7 neighbors didn't mind it, they thought they were a riot, and it's not like they carry on all day, or grate the nerves like a rooster crow can. They have 3 or 4 different types of quacks. The single, loud "Quack!", the single quack said multiple times, with a 3 second pause between, and the faster quack "scales", each one a little quieter than the last and then starting over. Then just regular mumbling quacks when they talk amongst themselves. But if they want to be heard, they will be.
The noise I could handle, they were cute. It was the mess and the time to care for them that got me. Felt like all my free time was going to ducks. Either I was cleaning the pool or cleaning the coop. Working full time, exhausted, and ducks to tend to daily. The chicken water lasted 3 days. The duck water, twice a day. Wet duck patties everywhere, not like the chickens that leave a nice pile under the roost you can grab real quick. I would throw fresh bedding over it, and use an off day for cleaning out the whole thing. The waste from all the pine shavings grew the compost by leaps and bounds.
But nothing is funnier than a duck standing on the ice of the frozen solid baby pool, quacking in contempt and pecking the ice. They're not amused by winter.
