Riddle! Comment guesses. (first post)

A victim of violence
Sometimes living in herds
I combine almost silence
With torrents of words
I must toe the line
Have to bleed to be heard
My path isn’t mine:
I’m a tagged and tracked bird
I’m casually eaten
If dead, bought anew
If I rest I’ll be beaten
Black and blue
I’m not worth much at all
On my own I can’t stand
I’m chained to the wall
Or I’m held in your hand.
