I think it depends on what is the cause, if it is a vaulted skull and therefore a Brain injury, the steroids will be needed, if it is the deficiency then the vitamins without should work. It seems to get a lot worse before getting better even when giving them the treatment, some mornings I would think he was never going to pull through!
Just a tip make sure that you do not have any deep water bowls because when it gets bad and they are dragging their heads along the floor if they get stuck in a bowl they will drown!
I used these as I couldn't get poly here!

I know there is slot of risks, especially hand feeding, but I had already lost one chick, and it is do anything or you are going to loose them anyway! X
Correct, if it is a thiamine deficiency, which it probably is , then all the other things aren't necessary . I've had silkies for 8 years , many with vaulted skull but I've never seen a brain injury. Mine free range with large fowl as well. Maybe I'm just lucky.
