Ducks missing feathers around eyes and on side of head

[Ducky0duck]

I recently rescued a pair of Pekin ducks that were in bad shape. They lived with chickens and arrived very dirty with poor feather health. The ducks are being fed Mazuri Waterfowl Maintenance pellet and were initially given one week of Recover 911 electrolyte then 5 days of safeguard wormer then a few days of VETRX Poultry Remedy. The Ducks health improved after the worming but they are still missing feathers around the eyes and the female seems to have lost more feathers on the side of her head. Any Ideas on what would cause this?

Thank you for rescuing them.
I know wet feather, dirtiness, and missing feathers around their eyes can all be caused by lack of proper bathing. I can’t say if there’s anything else going on, but they look much, much better in that newer photo.
