So then, if you don't wannt eat filthy, you have to eat home-grown chickens. I can't imagine a small breeder's chickens dying and then getting eaten without him noticing.
BTW, what's the problem with chicken eating maggots? Maggots are good protein. I see it as a minor failing of the Western civilization, this irrational phobia we have towards insects and invertebrates. Most of them are good eating, and not poisonous..
