HELP! my duck has clumps of mud on her face and her eyes are watering and red

[sugergertiedaffy]

Im super worried about one of my ducks, she looks to be in really bad condition and i don't know what to do. She has feathers missing and one of her wings is drooping but the thing i'm most worried about is her face. Her eyes are red and watering and her face is covered in clumps of mud and poo which i cant get out. I have tried to bath her but she scared and makes it very difficult. She's also quite old now so i'm worried about her. Despite this she is eating and drinking normally and runs around with the rest of the flock even if she is a little slower than them. If anyone knows what to do please get back to me as i need all the help i can get.

Pics would be helpful.

Ducks need access to clean water to blow out their nares, and can have respiratory issues if they don't. Can you offer her a clean kiddie pool or similar to swim in? I bet she'll clean herself right up.
