He does not go after anyone else. When she comes to visit once a week she goes down to the run and visits the chickens. Last two times he has started crowing and attacking her at knee level. She will walk towards him or chase him and he does not back off. So we have been discussing why this is and could it be her long curly auburn hair it's not red and its not black..could he think she has a hawk or something on her head? He trills at her and circles her and won't let the girls near her if they go for a treat from her he heads them off. When she sits down in a chair he circles the chair and dances. Odd behaviour but then he is my first roo.
