Well, I hog-tied the patient and looked in her deep, cavernous ears and then shined a search light down her throat, and all were pink, healthy-looking and normal in every respect.
I dumped some sample ear canal oil for itchy ears down her left ear, the one she always is scratching with her foot. So now I'm watching to see if that improves the head shaking. Maybe all it is is a case of itchy ear.
Thanks again for all the help. Chicken ears are awesome! And such cute, little pink, pointy tongues!
You are so funny. That is great news - when you looked in the ear you didn't see any black flecks (indicative of mites)? Hopefully the head shaking will improve now. Happy to hear she got a clean bill of health.
