I get my electrolytes at TSC and I get the bigger container because I give them probiotics and electrolytes when it is really hot - like today. I mix it into the water so everybody gets some. Every other or every two days generally. Advice from an old chicken keeper who made their own and used it during the hot, hot days. Its less than 7 bucks and lasts me a while. I am going to check out Cal Ranch and see if they have those mixes. Today's heat means I should do wet feed tonight with oregano and garlic. Hot here until about Wednesday then not much cooler. I'm expecting 115 degrees easily today. Here we go again folks. Stay safe and cool all.
