Seems that these are regulations which are drawn in such a way as to have unintended consequences. Surely an ordinary home, where someone is merely chopping vegetables and leaves the unwanted bits for the chickens, was not meant to be targetted. Can't see Defra bothering with trying to prosecute someone in that kind of case, however the Regulations are read. The Regulations are really aimed at commercial production, at factories or restaurants that might sell or dispose of waste for use as, or in, animal or poultry feed, not some householder feeding scraps to their own layers.
