Okay, so last night we had a lot of rain, and we haven't even prepared the ducks' shelter yet. Needless to say, the cage was a giant mud puddle when I let them out this morning. The white ones were all a little dirty, but my blind crested duck had turned from white to brown overnight. She was shivering in the corner, and there is blood on her left wing and on her beak, I took her up into the garage, and I really need to wash her off. What kind of soap do you use? I will look further into what's wrong with her wing, but I can't even tell until she's cleaned off. Thank you for the replies!
