Are these mites? And how should I get rid of them?

Saw these little grey bugs on some feathers in the nesting box. Are these mites? How should I get rid of them? I’ll try and post the video I took too

That definitely looks like mites. I would check around the vent of the bird(s), but that feather looks to be a pretty clear indicator. You will need to treat the entire flock. Most people recommend a permetherin product or Elector PSP if you can get it quickly.

Here's post from one of BYC's esteemed educators on treatment with permetherin:
