Does she make this noise only when you come around or can you hear it other times to? Does she get to bathe often? Feather quality can suffer from not bathing or from lack of proper nutrients or because they are to the point of molt where they will loose most of their feathers and grow in new ones. Bathing feed good quality feed adding some extra protein like kitten dry food and molting can all get feather quality going. Also if you can have a vet check her out. We can offer advise but can’t give a proper diagnosis because we can’t examine her. Also having one female to one drake can also play havoc on her over mating is very common with that ratio being drakes are wanting to mate so much. Best ratio would be at least 3 females to one drake.
