Mallard with trembling wings

[mothergooz]

I hope you all can help me, I'm very worried.

I went out to check my mallard this morning and I discovered her sitting at the side of the pond with her wings trembling. It was almost like she had Parkinson's. Her wings would involuntarily tremble about every 30 to 45 seconds.

Also her wings looked funny. Usually she has a very smooth coat of feathers, but today she looked as if she lost her primaries...her specula were exposed.

She was walking okay (no staggering), no apparent injuries, no blood anywhere, eyes were clear and she ate and drank normally.

Any way I can help her?

How old is she? What do you feed her? What's the rest of the flock like (number, breeds, drakes, flock dynamics).

Is she molting? Had she just been swimming? What's the weather like today and in the past week?
