I have a 7 month old RIR hen that is ruthless. Everytime my wife, daughter, or I walk near her, she chases and pecks your feet, legs and jumps up and trys to flog us. What in the world is her problem? She does not seem to be the Boss hen to the others and even gets attacked by other hens when she trys to attack us. We do not have a rooster. Could she be attempting to be a rooster? Any ideas?
