I had a chick hatched with similar symptoms. Head between legs and walking backwards even when dried and fluffy. I kept all of them in the hatcher and fed the chicks gro-gel on day 2. By the time they went in the brooder, I could not tell which one had wry neck. I hope that helps.Oh! Sorry I wasn't clear, so these two are the last to hatch out of a dozen! And this is my second batch of hatching chicks. All the rest are walking pretty much fine within an hour or two. This one is not even able to "sit" normally in your hand, it keeps arching and twisting and tucking its head under its legs. I'm concerned especially that it is not even capable of resting comfortably no matter what I do.
Thanks for the reply! I too don't have much experience but I know enough to know that what I'm dealing with isn't normal.
