Possibly something wrong

[The chicken nurd]

So one of my Muscovy ducks I noticed has dry dirty feathers especially compared to my other Muscovy otherwise she seems fine although she’s been half broody for a few weeks is this something I should be worried about I’m new to ducks so I could just be worried about nothing
Also I noticed this a week or two ago but didn’t think anything of it until I really looked her over today an realized her feathers didn’t look as good as my other Muscovy

 

[Feather queen]

the only thing I can suggest is to give her a container full of water big enough for her to float in, hopefully, she will give her feather a clean. best of luck
