if your pond freezes foxes eat call ducks . Feed it little and often , bucket full a day , if you over feed they can come any time if theres just enough you get a quick early flight as the duck race for food . Mallard can reach 9inches for food so dont worry about it floating , wheats or barley will do which evers cheapest . Go down early enough one evening and count them in from a distance . Put any hides up now , pallets wired to posts will do with some brash on them , or plant some willow wands around them and keep the tops pinched out
