I have a white EE Roo and he makes all sorts of sounds. He makes certain sounds at certain times of the day too. Only when it's dark in the morning will he struggle out a cock-a-doodle-doo. Only at night when the sun is setting will he sing like a songbird. Two days ago I hear what sounded like a stray dog nearby running around barking. My Roo was on watch and making little sounds then I heard the weirdest thing come from him. He mimicked the dog. He make this little woofing sound. I've even caught him clucking like the hens do when they've just laid an egg. He's a weird little bird, but very entertaining.
