I have a duckling that is now almost 8 weeks old, and is on 16% protein food, and he now suddenly appears to have angel wing?? Never had any of my babies get angel wing, and I heard it was mainly something to worry about when they're very young. Why so late, and can it be the food??? It's not high in protein. I'm really confused. Can he be fixed so late in life?
Pic and notice in the last one, taken on the same day, he's holding it just fine, what's up with that?
He's the mostly black one:
