mine spotted a big turtle in the yard the other day too. they all raced over and got up in its face and cocked their head sideways. you could literally see question marks above their heads. it was tooo funny. i have this one barred rock that chases mockingbirds. the mockingbird will land on a barbed wire fence and holler at her and the BR will run over to the fence and get right under and jump up at her. my barred rocks are also really bad about picking my locks and breaking into my house to get catfood. they are also probably the clumsiest birds i know though. mine dont sound like normal chickens either, they honk..
