Pekin plucking her own feathers

[jbeyer]

There is a semi-wild female Pekin on a canal near me. She has recently plucked a number of her own feathers above her wing.
The photos are from a week ago, and things have gotten much worse since.

The skin appears pink and healthy underneath.

Any thoughts as to what the problem or a potential solution would be?

Thanks in advance!

Cheers,
Jon
