I was wondering about this... because I remember reading on Metzers' site that if you feed ONLY 20% protein that it should be fed for a longer period of time than if you...
* If you cannot find a starter feed with at least 22% protein, then you can use a 20+% protein starter feed but you must use it for at least four weeks.
Injury or deficit... with that duckling gaining weight every day, I suspect it could continue to get progressively harder.
A crop injury adds another layer to this mystery.

Ornery kitty!
