Because you cant tell one duck from another and ducks keep reproducing , and because in the main, sick birds hide away to die, its not necessarily going to be visually obvious that endless white bread harms them. But in fact , the more healthy the flock looks, you could argue that thats because theyre all youthful ones - all others popping their bready cloggs after a couple of tourist seasons !

Parks all round the country are taking up the advice , its not just here. Yes they do as a service offer grain at a price , but theres nothing to stop you buying your own more cheaply if you get pleasure from feeding the ducks.
