Is this duck just weirdly shaped?

[MayhemsMom]

I have six khaki campbell ducks who are now around 12 weeks old. And Pots has always been... a little special. She would often take a tumble when preening her behind after a swim, a problem none of the other ducklings had. I worried about neurological issues or niacin deficiency, but in the end, she grew up the same as the others and has no balance problems now that I can see. But I have noticed that she seems, ah, differently shaped than the others, which may account for why she struggled a little preening as a duckling.

Is this duck just weirdly shaped, or should I be concerned? Let me know if more pictures are needed. The ducks aren't the most cooperative models (this is actually a still from a video).

Does she have any other problems?

Does she have any other problems?

Not that I’ve noticed. She swims fine, eats fine, walks fine.

Some individuals are just born with various defects or abnormalities, if the other birds are fine it is probably a genetic defect and not a nutritional issue. If she’s otherwise thriving keep her around, but probably wouldn’t hatch her eggs!
