Chicken Wisperer
Chirping
I do not know how long your chicken has been sick, but I do know that Wry neck is a vitiman deficiency usually passed down when the parent chicken does not have enough vitiman E. All the selenium does is help the absorption of the Vitiman E. if your chicken got injured, and this injury caused a condition similar to Wryneck. It sounds like a brain injury, that will not improve from the altercation between the two chickens. If you think I am correct in what occurred, then you need to reevaluate and decide if it is Wryneck or the injury. I really believe it is the injury causing the problems.
