So my Polish hen has been acting really strange. She tries to act like a rooster. She struts around and comes after me and my husband. You can put your hand in front of her and move it up and down and she will jump with it trying to peck you. I'm pretty sure she is a hen. She will be a year old in June and I haven't heard any crowing. I wish she would show that assertiveness with the other hens because they pluck her feathers out like crazy. Why has she gotten so aggressive towards humans?
