Does anyone feed their chickens kitchen scraps exculsively? I mostly have seen advice to use scraps as supplement or treats for chickens, but I thought I've heard of some folks that feed scraps only. We have lots of good fruit and veggie peelings and egg shells. I'm wondering if that is enough to keep them full or healthy since it would be nice not to have to buy unecessary supplies, ie feed and scratch. How necessary are the feed and scratch? Can our chickens live just on our leftovers?
