I am finding other post that are very helpful:
From shelleyb1969: I had a juvenile Silkie chick develop wry neck. I bought the Vitamin E gel tabs to treat her with. I cut the end off and squirted the liquid into her beak. After about 4 days I had to band her leg to be able to tell which one I was supposed to be treating. Her recovery was very fast...1 week and she was back to normal. I highly recommend you try it...it definitely can't hurt because it is treatable and curable.
From pontoosuc: Poly visol once a day, vit E once a day, some pedialyte in the water, and scrambled eggs, yogurt as treats. We did this for about three weeks, tapering off during week three. When she was having a bad moment, I'd gently uncurl her neck and hold it up for a moment or two which seemed like it helped a little bit. I did band her leg with a twisty tie so I could tell her from the other two Australorps. Left her with the others since it seemed that any increase in stress would set her off. One suggestion was to give the vit E with Selenium
but by the time I found it and bought it the capsules were not in liquid form so never did use any of it. Give it a try. Be warned you wear as much of the poly visol and vet E as the bird gets, if not more!
From three cedar silkies: This was the regimen we use:
Vit. E (400mg) snip the tip off a capsule and squeeze into mouth twice a day for 10 days, then every other day for another 5 days
Selenium (25mcg) dissolve one 250mcg tablet in 2 ml water and give 0.2cc once a day for 10 days, then every other day for another 5 days
Prednisone 1mg. dissolve one 10 mg tablet in 2 ml water and give 0.2cc twice a day for 5 days, then once a day for 5 days, then every other day for 5 days
B-Complex purchased in liquid form from Walgreens; 0.5 cc twice a day for 5 days, then once a day for 5 days, then every other day for 5 days
