I thought I would try our farmers market that meets at the town's common every Sunday. I wish someone from around home would of given me a shout in the where are u posting. I know there are people out there but I haven't meet any. That's why this is so interesting. I've had chickens for 2 years now and no one from any of the farmers aid stores have ever mentioned anything like this. They carry lots of bagged food thou! I now have the www.Azurestand.com catalog at home and even thou they don't have a co-op here, they could ship USPS. But I have to have some knowledge as to what I want to order. I guess I could call and speak to them. They should know about this? But I still need to know how much to much ratio.Unfortunately, unless you know someone who has ACV with the mother, you won't get the fermenting ingredients from ACV bought at the store. It's been filtered and cleaned up.
