Thank you for re-doing the photo!View attachment 1928745 Thank you. I will check it out. I brightened the photo so it’s easier to see her ear. I did of course immediately warm wash her face this am so she could open her eyes. And I did apply Neosporin to her ear and face. When I returned from work the “crud” seems to be coming from the eyes. But I imagine it must be from the ears as well as there’s no real wetness to either. Just crusty mucous build up. Seems like an upper respiratory infection for sure, like you mentioned. But can that come from mites? I’m guessing in my layman experience it’s just a coincidence that I found mites? I also cleaned out the entire coup and then treated it and my sick silky with food grade diatomaceous earth.

So the crud is still coming back and her eye is glued together overnight? Is it just on one side or is the other side like this too?
I would work on getting that crusty stuff off. For the ear, apply 1 drop peroxide, then remove the crud, sometimes it may come out like a plug. If the eyes are also getting crusty, flush them well with saline removing any debris and apply an eye ointment like Terramycin or you can use plain Neosporin.
I would still look inside the beak for mucous, yellow or white patches or canker.
If you feel that it's respiratory illness, then you can try an antibiotic like Tylosin to see if that makes a difference, but the crusty stuff and gunk in the ear still needs to be removed. Tylan50 seems to be hard to find, if you have that on hand, you can use that, if not then order Tylosin online. https://www.jedds.com/shop/tylan-soluble-100-g/
For lice and mites, it would be best to use a Permethrin based poultry spray or dust. DE is not that effective and a respiratory irritant.
I would also give her a direct dose of poultry vitamins that contain Vitamin A a couple of times a week. Poultry Cell would be a good choice for that.
