First time duck owner here! On Saturday I purchased 4 ducks and a drake from a friend. They are (I'm told) Blue Swedish. The drake is no doubt a drake (drake feathers). There are two blue/grey ducks with white bibs, a black duck with a white bib, and the remaining duck is all white. I had my suspicions that the white duck was not a blue swedish at all (bright orange feet and bill). Today I highly suspect "she" is not a she at all. Whenever the blue drake tryies to mate one of the ducks the white duck runs over and pushes him off. Then "she" will chase him away, all the while biting his neck. I even caught "her" mating one of the other ducks today. "She" is also a bit larger than the drake. Yesterday and today we got three beautiful blue eggs. If this white duck is actually a drake with no drake feathers it would explain the 3 eggs and the aggressive behavior. What do you think? These ducks are 6(ish) months old. Wouldn't the drake feathers be apparent by now?? Is it possible I have two drakes?
