I bought Tylan soluable powder just in case I ever need it. I only raise a few chickens and Turkeys for hobby. My question is, how much powder should I mix to a gallon of water. The bottle calls for the whole 100 grams to be mixed with a gallon of water, then for that stock solution to be mixed with 50 gallons of water. Obviously, I'm not a commercial farmer. Could someone simplify this for people that just need to medicate a few birds? Thanks very much.
