I went to tractor supply today to by some sav-a-chick vitamins and electrolytes for my new baby chicks, and they were out of it. The guy who worked there sold me some prairie pride v&e. How much should I put into a gallon of water? It's an 8 ounce packet. It says on the package to mix the whole pack to 110 gallons, but how much do I mix to just a gallon?
