in the uk, very occasionally, there is a feather or bit of chicken poo on your egg. nobody is really bothered or offended by this. american eggs, on the other hand, are power-washed to remove all traces of it, because in america, it is actually illegal to know about The Cloaca
@jk afaik that is also the reason why American eggs have to be refrigerated. The washing removes a thin waxy layer that keeps the egg fresh.
