Now, there's a difference to crouching and "squating". When they squat they will have their wings out slightly, as if to help balance a rooster. Occassionally one of my girls will even do a rapid stomping of her feet at the same time. If they are just crouching they won't hold their wings out. Mine crouched when they were too young but started squating once they reached maturity. They still crouch sometimes when I'm in with them and go to pet them once in a while, but the majority of the time the first attempt to pet them results in squating.
