Hello and welcome to BYC!
Glad you joined.
How old are your birds? I would hold off on the electrolytes and just offer the Corid water. If you have one that is much more lethargic than the rest, I would drench her directly with undiluted Corid. How much you give is dependent on her age/size. Just put a drop at a time to the edge of her beak and let it wick in.
Don't offer vitamins/minerals until after treatment is complete as any thiamine they contain will counteract the amprolium in the Corid.
