Apple cider vinagar from the grocery store is not the same as what we are talking about here.
I bought a gallon at health food store and used half to make my own. Each time I go to use that gallon I made i will half it and make another gallon.
If you use frozen apple juice it does make the cost...
How much vinegar do you put in a 2 gallon container ?
My health food store is the only place that carries organic apple cider vinegar and they want $11.50 for one gallon ? That seems pretty spendy for the chickens ! Yikes !
How often do you put it in the water ?
