Hi, This is my first experience with chickens. We ordered some Black Sex Links and picked them up 3 weeks ago. We ordered 12 and we got an extra one and it was different colored. I don't know if it is a different breed, like maybe a Red or if it might be a rooster. What are your thoughts... I know it is young and we may have to wait a bit to tell for sure. She or He is 3 weeks here. The same chick at a week old.
