Hello, I am trying to get the measurements for water and Duramycin-10 if anyone has any suggestions. It says on the package to mix 400-800mg to one gallon of water. Any help on the amount of what would equal 400-800 mg's ?????? I am guessing close to 1/4 teaspoons per gallon of water. Am I close enough?? I really don't even need a gallon but just to make it easier I thought I would go ahead and mix it up this way. I am only going to give it to one 2 month old chick.
