Feathers falling out with pus

[Duckpapawjames]

What is causing the duck feathers to come out and have a pus pocket where the feathers belong and what can we do to fix it?

More information like Breed, age, what your feeding with pictures of these pus pocket feathers will be helpful with determining what's going on with your duck.
