I will be getting three 4 week old light brahma hens in 2 weeks. I am getting everything prepared. I brought save a chick electrolyte and probiotic. It says they can be mixed together in 1 gallon of water. It also says mix a fresh batch every day. I will never use a gallon in a day. Each envelope of mix is .25oz. I'm wondering if any one else has run into this problem. What should I do? Do I make a gallon and use it each day until its gone, does it lose its benefits doing this? Do I attempt to try and measure some and mix it each day? I'm uncertain how much mix and water to even use?
