Im sure that pureed chicken bodies make good mulch, and maybe this would have avoided sentiment from activists if they had just killed the chickens (choked them, perhaps?) before grinding them up.

Or maybe they would have prefered to "set free" 30,000 chickens. That would have been a sight.

TrouserPython: That's an excellent idea, set all 30,000 free in PETA's front yard and see what they do.

That's cool. They couldn't do anything without causing irrepairable physical and/or psychological dammage to the chickens.

Actually, a wood chipper is probably the fastest, most humane method of killing off old chickens there is.
