Baby Chicks With Mites?

[Forkicks]

Question! I have some baby chicks that I'm pretty sure have some sort of mites on them. They keep picking/scratching at themselves, so much so they are starting to get some bald spots. What do I give baby chicks to dust bath with? Or if anyone else has any other remedy? I've never had this happen with chicks before.
Tomorrow I'm going to remove all the pine shaving and replace with new.
They are starting to feather out now and are about two weeks old.
Thanks for any help!

Will post pictures tomorrow if needed.

How old? New feathers coming in make them itchy.

Chicks will look like they are getting bald spots while their feathers come in.
They will pick and pull and preen. Will look kind of odd until they are fully feathered. This is completely normal.
