Welcome to BYC!
Can you post a picture of your hen?
If I have one overheat (usually after egg laying) I take her inside and put cool wet rags over her feet and under the wings. I don't put her back out until dark. And I watch them closely on hot days, from then on.
Electrolytes every day, can be too much of a good thing. Always make sure you have fresh, clear water available. Cool not cold.
And as @sourland says once you (or a chicken) have a heat event you will always be more susceptible to heat than others.
The symptoms of heat events are described by @BlueBaby I'd like to add pale comb and face, as well as pale skin inside the mouth.
