Yeah, I'm not going to lose any sleep over two rooster engaged in mortal combat.
BUT, I do understand the public nuisance and health concerns, not to mention the collateral crime that surrounds these kinds of events. Chickens are filthy animals. I don't think it does a local, suburban neighborhood any good having loud, filthy animals around.
I'm a part-time resident of the Miami area. Just a few months ago, my wife was driving down a large, 4-lane road and chicken hit her windshield, cracking the windshield. Chickens are all over Miami. It's ridiculous.
Keep chickens where they belong - in ovens and deep fryers.
