We have our Cayuga ducks next to our bedroom window and don't hear anything from them unless the Rouen drake comes up to their pen and then it is a quiet not even quack, just a "don't mess with me" throat sound. Then when I go out, he tells me they want fresh water in their pool, but other than that they are very quiet. I have a drake with 2 females and they are quiet. The mallards and rouens make the typical duck noise like Donald Duck did on the cartoon but it is not too often but definitely not quiet. The Cayugas are definitely quiet. Have fun!
