Chickens are individuals and have distinct personalities. Some sure do have more "going on upstairs" than others, but even then it is futile to compare their intelligence to ours; they are evolutionarily much different than we are, and as such have become suited to be adept at certain tasks and not at others. There is a lot to be said about what it is to be 'intelligent', but creativity in adaptation to survive and create optimal conditions for oneself is not the foundation of a stupid animal! To that end, most of my chickens are very adaptive, have shown the ability to learn and retain memories of situations that benefit (or stress) them, etc. One of my Barred Rocks, Chickadee, figured out how to work (undo) a simple latch to let herself out of the run!
Anyone that takes the time to observe chickens and their behaviors for what they are should see that they are not stupid at all. This involves having enough imagination to understand the world from a chicken's perspective. Hint: from a chicken's perspective, nearly everything would like to eat them, so they often err on the side of caution when dealing with new situations or objects!
