My wry neck chick had the same problem drinking and I gave him quartered cucumber as he could pick it well and swallowed easier. It is high in water content. Then 2-3 times a day I would drop water on his beak. I don't know what the right answer is about the milk-i know some give adult hens milk or buttermilk but I have never tried. I did try to help my little wry neck chick out of his "seizure". I would very gently straighten his neck and support him there for a bit and it did seem to help. It was almost like the more frustrated he got the worse his neck would get. I sure don't know if that's the right thing to do or not but I just couldn't watch him like that! My little guy hatched with wry neck and wasn't able to stand for more than 30 seconds until he was about 3 1/2 weeks old. He is a year old now and still drinks funny. He gets more water on his back than down his throat. Hope that helps.
