About 4 months ago, one of our 3 yr old Buff Orpingtons started twisting her head back and forth (like she's saying no) constantly. She moves fine, can stop doing it long enough to drink and eat, she can perch and navigate well. We took her to a vet when it started, he prescribed antibiotics, suspected it was neurological, but never gave a definitive diagnosis. The twisting has progressively gotten worse, and now she walks in circles sometimes. Has anyone else ever seen this? We are going to try vitamin supplements and treating her for ear mites, but I feel her quality of life is now not very good, so euthanasia is our next option. Just looking for any more ideas before doing that.I've read about Ploy Vi Sol ... what would be the dosage?ANd any ear mite medicine recommendations?
