Yes thats 2 ounces per two gallons..The dosage for wazine is 1oz per gallon of water, reguardless of how old or how many you have..Actually birds only need about 3 ounces of the mixture to be effective..But if you mix just enough, some will drink more than others leaving a few under dosed....one oz per gallon of drinking water, let them drink this in one day..
