I dont know if I am jumping the gun and making a connection between two unrelated incidents. However, I think I might be right. A while back I made this post https://www.backyardchickens.com/forum/viewtopic.php?id=512519. My chick was making head wobbling mainly from wind. It was weird. You can click the thread and see details. I treated it with poli vi sol. He got better. The same thing was happening with another chick but I didnt treat him with poly vi sol. The head wobbling later stopped but to my horror his head was upside down and he couldnt stand. Full blown wry neck. The chick died a few days later. Has anyone noticed a connection between head wobbling and later wry neck?
