I hatched my roo, and so my neighbors got to be accustomed to his crows as they developed. They all love him and the girls. Most of my neighbors are older and grew up with chickens, so it brings back good memories for them from when they were kids. My roo crows so long as there is light. If even one of my neighbors lights are on at night, he will cluck and crow... as if trying to tell them to turn it off so he can sleep. Otherwise he crows from first sunlight until the sun is back down and it's nice and dark. If you want to control how early your roo crows, you may want to invest in a blind. What I mean is... keep the chickens locked in the coop at night, and heavily cover all nooks and crannies, windows, and doorways so that NO light gets through. Taking it down (or opening it) when you're ready to start the day. This isn't a sure way to stop the early morning crow, but better than any. Your only other choices are... get a rooster, let him crow whenever, so what what the neighbor thinks OR don't get a rooster, and you don't have to worry about the neighbor at all. (I would get the rooster. They are so entertaining!)
