Incessant Quacking Female Pekin

[Phil7]

My friends have an adult female Pekin and she quacks incessantly at any time of the day or night. She and two other females are often separated from the two males because the alpha male has pecked all the feathers off their heads and necks. She quacks loud and long, literally all day, when they are separated. Putting them back together quiets her temporarily but she'll go off even when all 5 ducks are in the same place. Thoughts? Solutions? It's like listening to a dog bark all day long!

My females have their moments thankfully they don't last all day. But here is another member who had the same problem and there really isn't a solution, that's fool proof. But I'd def keep the females separate from the drakes this time of year but close enough they can see each other.

When you say adult how old exactly is she? I had a Rouen who was dropped off at my place around 2 months old and would NOT stop for months and months... Finally after she started laying she actually became one of my quietest birds and rarely makes a peep.
