Chickens are Chickens, aren’t they?

I don’t know whether to call them a Chicken Ranch or a Chicken Farm. But when I was invited to come and see this man’s chickens, and I went and was standing there, he asked me-

“Do you notice anything odd?”

I wasn’t sure. Chickens look like Chicken to me and they look best Fried, Roasted, or in a BBQ Pit. Do you see anything odd?

What’s so Odd? I don’t get it. Do you. A Chicken is a Chicken, aren’t they?
