The notice sellotaped to a tree on alongside the Peak Forest Canal at Marple reads:
Ducks need a
nutritional diet too.
Feeding white bread to ducks can
stunt their growth and prevent
them from flying. Give them
a healthy dinner of cracked corn,
birdseed or oats instead.
The nearest ducks I encountered were enjoying the manicured lawn of a house on the opposite side of the canal.
