If you wish, you may want to start your own thread about Peachy. Include some photos and information about her symptoms, what you feed, etc. For video, upload to youtube and provide a link.
Twisting of the neck does sound like a neurological symptom - some common causes are disease like Marek's, trauma and nutritional/vitamin deficiency. You can try vitamin therapy to see if that helps. Give her vitamin E and B1. This is easily done by providing 400IU Vitamin E along with 1/4 tablet B-Complex once a day.
