* A baby duck is called a duckling, and an adult male is a drake. An adult female duck is called a hen or a duck, and a group of ducks can be called a raft, team or paddling.
* All ducks have waterproof feathers as a result of an intricate feather structure and a waxy coating that is spread on each feather while preening.
* All domestic ducks are descended from either the mallard or the Muscovy duck.
* There are more than 40 breeds of domestic duck.
* The production of eggs is affected by daylight. When there is more daylight, the ducks will lay more eggs. In the months of September to December when daylight is short, they slow down their production of eggs. Sometimes, ducks stop laying eggs completely during these months.
* The ducks mouth is called a bill. It is usually broad and flat and has rows of fine notches along the edge called ‘lamellae’. The lamellae helps filter out the mud and silt and allows the duck to grip its food so that it will not slip off.
* Duck eggs will hatch within 28 days normally, except for the Muscovy duck which takes about 35 days to hatch.
