Hi, first question: why can't I use the apple cider vinegar in my kitchen cupboard, why does it have to be "raw" to add into the chicken's water? ( I read that on another thread, but it wasn't explained). second: is there an automatic feeder idea anyone can recommned? We camp during the summer, and I feel tied to my house because of the birds. They begin making noise early, and my neighbor's are twenty feet away, so I try to feed the birds early, at first light, to minimize any noise. If I go camping, we can get people to feed the chickens, but not at first light. I love them, but it makes going away for a few days a little stressful.
