I have a 21 week old hen with what I think is wry neck. I got a different food the last time I bought it and I think it was lacking in vitamins. She is going down hill fast. I found her yesterday with the classic twisted neck. She's not eating or drinking so I have been giving her vitamin E suppliments, electrolytes, and water with a syringe. I tried crushing some crumbles and watering them down a bit to feed her, but she acts like she is choking. Today her neck isn't twisted but she still can't hold it up. She's not opening her eyes. She does however fight like a mad woman when I take her out of the crate to give her water and such. How long should I give her? It seems like she still has some fight left in her but she's definitely struggling. Any advice is greatly appreciated.
