Hi! You can definitely use this for broiler chickens. Shake well. On day 1 and 2, run 12 ounces of Mother Load apple cider vinegar per gallon of water in a medicator bucket set at 1:128. For the next 2 weeks, run 12 ounces per gallon of water for one 24 hour period per week. Through the rest of the grow-out, run 6 ounces per gallon of water for one 24 hour period per week.
