I know of someone who has a pet rooster. He has acerage out in the country, but not a farm. One day, this rooster just sort of wandered onto his property and started following the guy around, so he kept him. Apparently he is a very social and loyal pet. I've thought about having a pet rooster, but I think barking dogs are bad enough, I definitely couldn't deal with the noise of a rooster!
I have also considered a pet skunk; they're so cute and people say they're relatively similar to a ferret in behavior. But of course I couldn't have my skunk and my fox at the same time!
