Pekin ducks are very similar and look the
same. However, there are some simple ways to find out the gender of your duck.¬
One way is to examine the tail of your Pekin. Males will have a curled feather called a
drake feather , while a female’s tail feathers will be smooth and together.
Another simple way to find out if your duck is a he or a she is to analyze the sounds
they make. Males will make sounds that sound more like squacks than quacks. This is what
they sound like. … Females quack though, which sounds like this….
Also, males tend to bite the back of a female’s neck and stand on her while mating, so the
duck who shows this “biting the neck” behavior will probably be the male.
