She has well water. You wouldn’t drink well water from the tap? We get ours tested annually, and drink it right from the faucet. Thankful to be off city water!Be very careful of the water you give them!
Never use tap water, for the very same reason we as humans rarely drink water straight from the tap. You don’t need to give your chickens Bottled water, but you do need to let the tap water rest for a day before giving it to the chicks. You can speed up this process by either boiling the water or putting it out in the sun, which dissipates the chlorine and other impurities in tap water.
I’ve never used electrolytes and I’ve never experienced the problem you’ve described.
But we all know how bad tap water is. Let it rest for several hours and dissipate.
Older chickens will have no problem with tap water, but these are babies!
