Mites on ducklings? Missing feathers around eyes

[MshVT]

I just picked up 4 call ducks that are about 3-4 weeks old. When I got them they had just taken a bath and were wet. Now that they’re dry I see that they’re missing feathers around their eyes. This is only on the 3 yellow ones. I have a brown one that looks fine. These are my first ducks so I’m unsure. Is this mites? I want to be careful not to pass anything to my flock of chickens. Any advice would be great.

Looks more like the feathers are rubbed off. How were they kept?
