@elebertus @ai6yr In our case, it's a noise issue. Roosters are only allowed in low-density population areas. Where I live, livestock is permitted but in limited numbers. And no loud animals...I can have chickens or cows or horses but not roosters or donkeys. These are County rules, which can be made more strict by individual cities (I don't live in any city)
Historically, the county had a lot more ranching and farming, so the rooster rules are probably pretty new.
