My rooster Roopurt, a buff orphington, has a flock of about 12. However when I introduced a few new ladies to his flock, including a brown leg horn, he has seriously rejected one of them. Freak of nature, the brown leg horn. She lays eggs, so shes a girl, but he chases her away, attacks her, pecks at her, and wont even breed her??? She tries to present herself and he ends up kicking her. Is this normal? Should I re-home the poor thing? Or will he get over it?
