Does this look like mites?

I attached photos. I haven’t been able to inspect all of the chickens but this one has these white flakes in her feathers and she’s also been molting. I compared it to pictures of mites on google and hers look more flaky than the photos I saw. The other hens also have some white flecks on the end of of some of their feathers. And some of them have pale combs but I’m hoping that’s just cus they were molting. I really hope it’s not. I did spray their coop with a preventive spray and replaced all their bedding last month.

To me it just looks like the coating of the new feathers coming off. Very normal

It's shed feather sheathes and dander, nothing to worry about. Typical for molting birds.
FYI: Lice are white, off white or straw in color and you can see them moving around in feathers and fluff or on the skin. Sometimes their eggs are attached to feather shafts particularly around the vent area where it's warm and moist.
Mites are black or red in color and suck blood. They move slowly and have 8 legs. They can cause anemia, then death.
