I have 14 six week old chicks in the brooder. I have been so proud that even though this is my first flock of chickens my chicks have grown up trouble free. That is until a few days ago my delaware hen started acting kind of funny. When she walks she holds each leg up for a second before she puts it down. She also seems to twitch and shake once in a while when she is relaxing. It is kind of like she has turrets syndrome without the cursing. Is it possible that she could have a virus that is now starting to affect her as she is starting to mature? I don't know what to do to treat her and hopefully help her get better if possible. It is like there is something wrong with her nervous system. I have seperated her from the other chicks just in case but don't know what to do. Any suggestions?
