Don't put anything on her without advice from the vet before the scrapping. Call and ask before you do anything.Thank you all for your support. I haven't heard from the vet I called this morning, but I just made an appointment with a different one - an avian expert, and will get a skin scrape. Unfortunately I can't get her in until the 20th, but I'm on a waitlist for cancellations. I will order the permethrin and give that a try too.
