Vinegar

[2dancingrats]

How much vinegar do you use in your chickens' water?

 

[TigerLilly]

I believe it's supposed to be 1 tablespoon per gallon, but I usually use a little more apple cider vinegar.

What is the purpose of the vinegar?

 

[dawg53]

Apple cider vinegar (ACV) is an acidifier which helps in calcium absorption and lower gut PH (to help with bacterial issues.)
