I have our chickens free range with our hogs, the hogs get grocery store vegetables and fruits that are being tossed. The chooks will peck at some things but they love any raspberries, blackberries, blueberries that come along. They will also eat the squash, melons but since they have to compete with the hogs for these items, they don't get so much as to be a problem. We feed the chooks meal worms, grasshoppers, crickets, and what bugs they catch as they free range. They love most greens and figs that are over ripe are one of their favorites. I also toss them any tomato horn worms I find on our vines, they fight over those. They also love to steal the golden hog feed that we put out once a day. I calculated the protein per day for both the hogs and the chooks came out at 20% protein per day. the hogs were at 18% protein per day. They both have free choice minerals and the chooks have lots of grit and calcium available too.
