Not wry neck. Wry neck causes an imbalance to the inner ear. They will go side ways not front to back. Silkies, especially vaulted skulled ones are prone to head injuries. As are polish. The vaulted skull is a protruding of the top of the head. It is not a closed skull, therefore the brain can easliy be injured. Sometimes newborns will get the same symptoms if pecked just once by a hatchmate. This was a topic of discussion at a recent show with a masterbreeder & judge of silkies. The best treatment is to just keep her by herself. Making sure she eats and drinks. It will resolve itself after the nerve endings have had a chance to repair. But caution, if not properly repaired,the symptoms can show up, if the bird is under any stress. ie back into a coop of others to soon. Some birds will appear fine for months and then show signs if under stress. Next time at a show, watch the silkies that have been there for a few hours, some will start twitching their heads about, like a bobblehead. They have had some type of head injury in the past. Sometimes the injury resolves itself before the owner is aware of it, but is only noticed sometime later when the bird is stressed and begins to Bobble. Having breed silkies for awhile I have seen this happen often. I just this week had a newborn do this the second day after hatching. I left her alone with the others and in two days could not tell her apart from the other chicks. I also had a cock injure himself on the way to a show. He was fine when I put him in the crate, but once we arrived. His head was tipping forward and bobbling. I brought him home and put him with his hen, who acted like a seeingeye bird. She would help him stand for food and water. She would walk up to him and lean into him and cluck when I would add their meals. After about 4 months he was totally back to normal. Hope this info helps.
