Been feeding a pond now since august 1st and there has been plenty of ducks (all mallard) on there up until last week, were the total count was about 70 birds! But the last few nights numbers have dropped. With only about 15 or so tonight! what do you think it could be? over feeding? rise in temperature? as it was alot colder last week? It is not a large pond only about 12 x 6 meters. any suggestions ?????
