Evil Chicken

Miles was sleepy and had his head resting on my shoulder as I unlocked the front door.   A small group of birds (I don't know what kind) were hanging out on a small tree in our front yard.  When a big truck drove by the birds all took flight and made a loud chee, chee, chee sound.  Miles was startled and screamed, "Aah!  The chickens is coming! Hide!"
