Everybody has to decide how they want to handle it. Since I am allowed roosters here in my rural county, then I will have them. They're allowed dogs and ATVs and guns and they have them. Those make noise, my roosters make noise. I have three adult roosters at the moment and don't plan to get more, but they crow. Can't stop them, can't train them not to and there are roosters all around us in every direction. So, my rooster's noise isn't an issue in this case, even if they tried to make it one. Everyone exercises the right to enjoy their own property within the bounds of the law (and sometimes outside those bounds, it seems). The law says I can have chickens, including roosters. The law says their dog cannot roam or kill/harass livestock or poultry. It also says they can't make threats then follow through with taking a loaded gun onto my property to do violence to me or my animals. Seems pretty simple in this case. I do have nice neighbors, most of whom say they love hearing my roosters crow, including the kid's very elderly grandmother.
Found out that the kid has a job near here... at a chicken processing plant. May skew how he feels about my birds, considering he inspects FrankenChickens all day long. Guess he's here for the time being. Oh, joy.
