They both seem very similar to me and I have been treating my 5 day old baby chick for wry neck. Her neck is not twisted backwards like most cases I have seen, but she walks backwards, loses balances, and her head spins in a circle. She is still eating and drinking on her own and I am giving her vitamin supplements. I also hear clicking when I take her out to give her her vitamins and I have linked that to a possible respiratory infection. I am using VetRx in her water for that. I have a separate thread on this but I just want to make sure I am treating her for the right thing.
