I have a 16 week old Lavender Orpington chick with wry neck. I have read the posts about Vitamin E and selenium along with Vitamin B. While her neck is bent to the right, the left side of her neck/shoulder seems to be enlarged. She also scratches her head on the left side. Is this a symptom of wry neck or is the swelling an injury that is causing the wry neck. And is it treatable? Thank you for your help.
