Feather return after mites

[old mama hen]

In the many years of raising chickens I've never had the problems with mites like this year. Have used diatomaceous earth and neem oil, cleaning the coop and changing the nesting flakes out. The majority of the hens and rooster have their feathers returning. However, I have 3 or 4 that I see no sign of feathers returning. I'm really concerned as colder temperatures are around the corner. I am continuing the dusting and needs oil dipping and spraying. Any suggestions?

It's molting season, everyone molts at their own rate.
May I suggest not using DE? It doesn't actually take care of lice/mites, & it's terrible for the lungs. If you want to kill mites/lice successfully use Permethrin Spray, or Dust.

Are they also molting? Are you sure it's mites?
Have you cleaned out the coop completely, treated it and gotten all new bedding and litter?
I would recommend you stop the Diotomaeceous Earth, it's not effective for mites, causes skin dryness/feather breaking and it's like breathing asbestos for you and your birds.
