I am new to chickens and we are experiencing a behavioral issue. One of my Wyandotte's is crazy. She loves the hen house, if I flush her outside, she runs back in the house, saying "ouh ouh". She heads to her favorite corner and buries her head, facing the corner. What is with her? She is not the only Wyandotte, but the only one of 12 (Wyandottes, Black Sex and Rhode Island Reds, one rooster) that behaves like this. My next question is, why do they peck on each other? They starting to have spots where they are raw. Do I need to treat this area? They were all born in April and started laying the first week in August. I am getting 5-10 eggs a day. Someone is really good at laying double yokes. Any guessers who?
