I actually already have a no-crow collar and thats why he is so quiet. To quote the Animal Control Officer I spoke to today while looking for advice, "Roosters are legal but the noise they make isn't." Hence why I'm looking for advice contesting it. He is now at or below the decibel level of most other neighborhood noise(cars honking, children playing, neighbor-the one complaining- talking on her phone on her porch at all hours, dogs barking, etc.) and according to the City Noise Ordinance, his crow is infrequent enough that he doesn't violate anything at all. He only crowed three times today.
So you see why I'm looking for advice. My neighbors are making unjust complaints, and I know I will need to fight them to keep my sweet rooster where he belongs, with his flock.
There are free decibel meters for phones. I would download one and measure his crow from the same distance a your neighbor's house. I would also measure and document normal neighborhood sounds (dogs, traffic, kids playing, etc.).
