I remember hearing, back in the early '60s, one instance where in a Japanese prison camp during WWII, prisoners would go thru diarrhetic excrement looking for undigested rice.
I don't think that anything can be worse than that.
I read a stockman’s magazine article about cattle feed. Worse than Chickens.
When you get around to it, chicken is the perfect food. And, yes, I have been wondering what would happen if a couple of MR chickens suddenly disappeared. Not that I would, of course.
Maybe.
