Runner ducks are quiet when they forage. Most of the time you don't hear them. Sometimes the drakes quack softly. Sometimes the ducks make soft noises of pleasure if they find a cricket.
The drakes are never loud, they cannot quack loudly. The females only quack loudly if they want the drakes to come. This is rare, since the ducks all stay in a group. The ducks will sometimes quack loudly when I come out if they are out of food. It is embarrassing, but if I quack loudly all my ducks come quickly. So when I want my ducks to come in after they have foraged for a while, I have to quack loudly. I am the only duck that disturbs my neighborhood.
Runner ducks are funny. When they are hand-raised they are trusting and you can have fun with them. They are active so you are never bored watching them.
Runner ducks have long necks, so they give the best duck hugs. Runner ducks give duck hugs by leaning their heads against you.
Runner ducks lay eggs early in the morning, so they will rarely leave their eggs in the field if you let them forage during the day. This makes gathering eggs easier. I recommend runner ducks!
