Ok. Hope folks see this.
See my two other threads on this issue. Been trying to figure this one out for a while now. I need help pretty please!

She's now been treated twice with Elector PSP 2x and I'm pretty sure, after examining her feathers this afternoon, that she still has something going on. I wasn't sure if her feathers were getting worse or not, but I don't think these quill mites are gone. They are in the follicle of the feathers, and eating through the quill I think. In the morning there is a dusting of what looks like chewed up feather quills all over the roosting bars and droppings board, too. I'll try and get a photo of that too.
I can get Ivermectin, the 1.87% paste, but not sure how to dose her. I've read some threads about it, but I still don't understand fully
I also have permethrin powder, but I'm new to both of these, so any need help on how to administer and dosage, and which one I should use would be greatly appreciated!
