Chicken Boxing is cockfighting with the deadly rooster spars covered by rubber snap-ons. It is illegal but who is to say what consenting chickens can and cannot do?
Boxing chickens are expensive, often selling somewhere between $2500 and $25,000 dollars. So with a $25,000 chicken how much fighting is needed to turn a profit? I dunno.
Even if the chickens are not killed or maimed in the process the argument is we as human beings should not be profiting by viewing violence. So much for the NFL.
