Welcome to BYC. That does look like a type of wry neck or neurological problem. Vitamin deficiency, head injuries, and diseases such as Mareks disease and others can cause this. Here is some reading:
Vitamin E deficiencies can cause a condition called Encephalamolacia. It usually effects young birds but can be seen in older birds. Give one vitamin E tab once a day for 5 days while using a good vitamin-mineral & probiotic powder in the water. You can also give 1/4 cc of a vitamin AD&E injectable in the breast muscle. If there isn't excessive damage to the bird's brain from swelling, that should solve the problem.
Don't feed too much cod liver oil (should never exceed 3% of diet). Stay away from rancid fats and expired/rancid feed.
