what an awful thing to want to do to a chicken!!! I find that it is creepy when people enjoy the fright or pain of any animal, human or non- human. Pretty sure this isn't just me.
It was a joke. No one was seriously thinking of feeding their chickens Pop Rocks.
Folks, it's a JOKE. Where's your sense of humor - neither BBQJOE nor anyone else intends to feed Pop Rocks to their birds.
