What is the vet testing for? The most common cause of this is MG, which is treatable and not curable. Your surviving birds become carriers.
If you want to medicate get TylanD50 for a feed store or Tractor supply. You can inject the birds or put it in their water.
I've seen posts like this where vets don't check for MG and it ends up costing a lot of money and dead chickens. Call the vet in the morning.
