Permethrin..IF you actually have external parasites. I do not treat unless I see them with my own eyes, many other things can cause feather loss.I am having a similar problem. Mine are pulling out tail feathers. If it is mites, what do I need to do to get rid of the mites?
And after you use all the 'natural' stuff, you can get some permethrin to battle the infestation those things will allow to fester and grow.This page is full of great information: https://www.fresheggsdaily.com/2013/02/mites-how-to-prevent-them-and-treat.html

Have you checked them over real well for mites and/or lice?
Best done well after dark with a strong flashlight/headlight, easier to 'catch' bird and also to check for the mites that live in structure and only come out at night to feed off roosting birds.
Google images of lice/mites and their eggs before the inspection so you'll know what you're looking for.
Wipe a white paper towel along the underside of roost to look for red smears(smashed well fed mites).
Part the feathers right down to the skin around vent, head/neck and under wings.
If you do find some...check out this thread:
