if I had noticed that my own rescued commercial (cornish Xs) birds were as dumb as a box of rocks. About ten years ago there was a terrible ice storm in the area and she ended up with a ton of them after the ice destroyed a commercial house. I tried to defend these poor birds by talking about how sweet and docile they are, but in the end I had to agree with her. I love my little meaties to death, but they are so dumb it's pitiful. They make your average backyard birds look like genuises.
