We're looking towards growing our own grains to feed our girls, there's a fantastic YouTube video on this from a woman who really crunched the numbers. I'll try to find a link for it. but we live in an isolated place and sometimes run out of feed. We feed them ground beef, grass clippings, sweet potatoes, squash, crab apples, clovers, rose hips, herb clippings, quinoa, pasta, black beans, scrambled eggs,canned diced tomatoes cayenne pepper and sea snails when we need to forage for feed. We don't free range as we're in mink territory and he's gotten them before in broad daylight when we used to.
