This 12 week aracauna (who was supposed to be a female) is REALLY mean! He is always attacking anyone around him, I often find feathers in his beak, so he is pulling hard! Sometimes, if I catch him I will chase and yell. Is there anyway to alter his behavior? I would like to be able to keep him, but I don't want such a MEAN roo. Suggestions? He is an interesting looking guy.
