I wouldnt consider them loud by any means. I mean, they do make noise, but nothing like our crowing roosters! And it isnt constant either- ours just seem to want to "talk" to us. They come running over and start "barking" at us-that is what it sounds like to me. We never hear a peep after dark either, so they arent going to be waking anyone up. Maybe there is a difference in breeds though? We have Narrangassetts & Bourbon Red-the Black Spanish we had (but was eaten by a coyote) wasnt partcularly loud either, and he was a tom. Unless you have super easily annoyed neighbors, I would think most would not find them a noise nuisance-unless you had ALOT of them. 2-3 wouldnt be a big deal. Now, the giant turkey poops on their front steps might bug them a bit...
