So would I!
They sound a lot like horses, who also have herd hierarchy, and some individuals who are willing to challenge for it while others just want to know their place and still others are more or less solitary grazers. Sometimes a new horse joining the herd will want to throw his or her weight around and be the leader, as he was (or wasn't) in his old crowd.
I once saw a fascinating program about a guy who spent a year with a flock of turkeys he raised from eggs. I think it was in Florida? After the year with the turkeys he moved to another state to live with another group of animals, I think.
I think that's why some horses are good at racing, they like to run with the herd (and some are more willing than others to get out front and "win").
