Duck's Wing Twitching and Fanning Out. Can someone tell me what this means??

[Pamuk]

This is fascinating. It doesn't seem like she's in any kind of distress, from the video. Is it possible to get one of her doing that retching motion you mentioned?

She's usually very fatigued, panting and her voice goes very raspy barely able to quack which is why she tends to be very quiet during this time. Accompanied by the wing twitching/fanning and retching. She's fine now, like i said, she usually goes back to normal within a couple of hours. I'll try to get a video of the retching next time.
