I'm sorry to hear she is not improving.
9 days is a long time for her to be like this, does she indicate that she is in pain?
Again, Wry Neck is symptom - it's not always caused by vitamin deficiency.
While vitamin therapy is really the only treatment, sometimes it's ineffective. Since she has gone on so long, I would consider the cause to be Marek's. Some birds can recover, but others decline or linger for a good while.
I've included links below about tube feeding, that should give you a good idea of how much and how often you need to be feeding her. A sick bird does take time and patience, so all aspects should be considered - her quality of life should come first.
I suggest you read about Crookneck/Wry Neck in the following article, it details the vitamin therapy hopefully you will find that information easier to follow http://www.browneggblueegg.com/Article/Crookneck/Crookneck.html
Here's some further reading for you about Marek's and tube feeding
