chicken or rooster?

Yesterday, I am driving by my neighborhood park. I always look over to see if there are any kids I know playing softball. I used to take my dog to this park, so I always like to look at the people with their dogs. Well, on this particular day, as I am looking over to see what I can see, I see a guy walking a chicken! He was just walking along with this chicken by his side. I asked myself "was that guy walking a chicken?" And then it was like my mind couldn't comprehend what I saw and I never thought of it again until just now (a day later.)
It got me wondering what this guys house looks like. Does he have a wife? Does she ever walk the chicken? Is this legal? Does he give the chicken a treat after their walk? Does he carry a plastic bag for the chicken poop?
I think I was better off before I started pondering the chicken walker. Sometimes our minds know when to just view something and then never think of it again. This one crept back up on me.
