On: Are fish more intelligent than we realize?

[derrekl]

I think animals raised in captivity lose a bit of their intelligence because they don't have to do anything to survive. If you go to Kauai you'll see wild chickens running all around, and while not brilliant, the ones that made it this far along seem pretty smart. Chickens survive fine in the wild so long as there's no snakes to eat the eggs they lay.

Also: rats, raccoons, coyotes, raptors of all types, feral or domesticated dogs, feral or domesticated cats, and the occasional car.

Chickens do just fine if there are no effective predators.
