Duck Losing Breast Feathers

[Disheygirl]

New to ducks with two that are about two months old. The female is losing a bunch of breast feathers. The male isn’t, and she isn’t losing them anywhere but her breast - they’re all the same small fluffy feathers. Is this normal or should I be looking for parasites? Don’t see anything obvious.

I would always check for parasites, but since she's so young it could just be a growing molt.
