Life is too short to put up with cock birds that are aggressive towards humans. If you only have one though, I'd suggest putting up with him until you can hatch some more, and then cull him (and any of his sons who are mean, aggression is a heritable trait.)
The only time I kept a mean cock bird was when he was so valuable that I couldn't cull him. But once I had some of his sons, he made lovely soup.
