yea I know where you are comming from. I have a suburban style house and when we moved in the neighbour introduced himself be handing me a sack with a rooster in it, really not what we were after but so far none of the other neibours have complained lol. We had to take measures the other day to delay his morning crowing (changed the roost) which helped heaps, but the bottom line is roosters are just not great for inner suburban areas lol.
Try posting a pic of you bird when s/he is ~6-8 weeks old. It seems like lots of the expert chookers on here are pretty good at sexing from around that age if they know the breed and exact age.
Good luck and my fingers are crossed for you
