As I see it, and this is only me, theres a difference between working out "problems" due to conditioning and true cognitive reasoning. If you hit a chicken with a bat enough times, it will avoid the bat. But until you do, the bat wont be perceived as a problem
Me, I don't need to be clubbed even once to know it will hurt.
The Bird is far more capable than we used to imagine, that I'll agree to. It's ability to learn a behavior and "social relationships" within the flock make us all the more aware of such dynamics among other animals, especially birds.
SO yeah, there is more going on with the dumb chicken than many will admit.
And the day a chicken builds a hospital, bombs a village or paints a masterpiece, I'll be first in line to buy a ticket. Until then, we wait.....
Good post, though. I've always enjoyed it.
