My cochins/pekins love to talk--but their clucks are very soft and quiet. My rooster's crow is pretty quiet too, so if you do end up with a rooster he shouldn't bother you or your neighbors.
I like having a bachelor pad. It allows me to keep a lot of breeding roosters, and grow out cockerels. If you plan on having over 4 roosters, I would make a bachelor pad. If you plan on having 4 or less roosters, I would split the roosters between the two coops with groups of hens.
Some docile...
