Silkies are probably a good breed for you, just don't get roosters. And if any of your neighbors see them and ask what they are, just tell them it is a rare Chinese bird.
(I don't think most people would recognize it as a chicken.)
I am actually surprised at how quiet my ISA browns are. I expected a lot more noise. The only time they even get loud is just for a minute or so after they lay an egg. Even when I bring them a treat, the sounds they make are very subdued.
Now my neighbor has a rooster, that you can hear crowing from a block away. Another has a goose that you can hear from quite a ways as well. The noisiest critter in the area is a donkey. A couple times a day you can hear it braying. That sound probably travels a half mile or more
I love the sound of all of them. Not everyone dislikes natural sounds. Sure beats those "boom boom" cars that you hear from six blocks away.
