How are the rest of your birds today?The feed is Purina medicated chick starter feed, which treats for cocci.
The feed store now thinks my electrolyte solution was too concentrated...so in essence I slowly poisoned the chicks. This increased strain on their hearts, when paired with the high altitude of Colorado, resulted in a perfect storm that gave them ascites, or "water belly." Apparently this is much more common than I thought. Anyone who experiences water belly with their chicks, this is an interesting general info article:

Hopefully pure water and a close eye over the next week will save the remaining chicks.
**Warning for anyone using a general electrolyte solution suitable for all livestock - DO NOT follow the dosing instructions on the bag. For chickens, a pinch of granules per one gallon of water is all that's needed.**
