I just picked up my new 6 week old to finish my flock of 5 and after reading posts, I think it has Wry neck. It is too late to treat it? How much, How often.....She is so sweet and I want her to live. She's not twisting, falling down, etc., she just has a z in her neck and it hangs down when I pick her up. She closes her eyes too. She also leans to her left side when laying down, maybe because of her neck??? Help. Thank you.
