My two pekin ducks, Johnny and Baby, tend to wag their tails a lot, why? Is it happiness like a dog? Being annoyed like a cat? A mystery? Also they stand up really tall and shake their wings a little from time to time, why do they do that?
a little like that, but a duck and still in a standing position.
I doubt it's something bad, I'm just a little curious...
