What do you guys think of this? Personally I've had pet chickens before, and they were pretty smart. Mostly just concerned about food, but most animals are, especially considering ours got a huge variety of yummy food. One used to run up to me for scratches, and treats. I tried clicker training her, but didn't have anywhere to train. My whole yard was grass, and she was smart enough to know that it was easier to peck at the grass, rather than have to work for the treats I had in my hand lol, and I had nowhere without grass to train... But she was starting to get it before she died.
I think people only judge others intellect by seeing how well they communicate with humans. This is totally unjust. We don't communicate well with other species either.
