Great question!!
You got some good advice here; plain water is adequate.
When I started with chickens last year I also worried a lot about nutrients in water, probiotics, type of food, and so on. With so many supplements marketed it raises questions in my mind, still today, if I’m doing the best for my flocks. Chalk every interaction up to be a learning experience.
I hope this offers you some reassurance that using the electrolytes water as you did didn’t cause any harm. Like children, the next round of chicks is easier and we worry less. Good luck with your flock
