In my experience, they don't begin to get aggressive until they get older. A 5 week old chick is more like a 5 year old, and a 16 week old is more like a 16 year old. That's when the hormones start kicking in and they start getting aggressive. And then after a year or so they start to calm down a bit more and be more gentlemanly. So just be prepared for that as he gets older.
