I would definitely talk to your neighbors first. All it takes is one neighbor who wants to be a pain to call animal control and they will make you get rid of them. I would let them know that you are not getting a rooster and if they have any issues to come talk to you first and you will handle the problem (i.e. smell, noise, etc.) If you let them know ahead of time they are more apt to be supportive. Congratulations and have fun.
