Sexing a Duck by the Quality of its Quack
can determine the sex of a duck by listening to
the sound of its quack.
At about 10 weeks of age, the voices of all domestic ducks
(except Muscovy ducks) take
on easily distinguishable male and female characteristics.
The voice of a female
(hen) is a loud "Quack-Quack!" or
The voice of a male (drake) is soft and whispery.
They sometimes even have a slight whistle until
they reach full maturity.

There are rare occasions when a hen will sprout a deceptive
curly tail feather. This tends to occur when there are no
drakes in the flock. Sometimes one hen will temporarily take

during this time, you may be temporarily fooled into
believing you are seeing a hen--until a new tail feather
grows back in anyway.

feathers on their crown).
Muscovy ducklings peep just like any other duckling.
As ducklings, male Muscovy ducks often have larger feet than

size and appearance, as they age, males grow noticeably larger than
females and have more elaborate and bulbous facial masks (carnicles).
Juvenile male & female Muscovy ducks have a black dot on top of their head
that fades away as they mature.
