RE: Chicken food scraps, raw potatoes: Green potato skins and "eyes" on potatoes contain toxins. There are lists online and in books of foods/plants,etc. that chickens should not eat. Don't give them anything moldy. I was worried last summer because we had eggplant and tomato plants, which are both toxic to chickens, but they seemed to know to stay away from plants/berries that they shouldn't eat. Crafty chick said that hers stayed away from orange peels, which is another toxic food. And avocados are very toxic. I mentioned "hardware death" before, and Leahs Mom brought up keeping an eye out for little pieces of glass, plastic, little nails, staples, etc. (Be especially careful about cleaning up hardware items when you are building a coop). While doing yard work with the chickens' help, I almost always run across remnants of my kids' childhoods-- little plastic beads, broken toy pieces, pieces of ribbon that the chickens might eat.
Since I only have five hens, for treats I give them cut up blueberries, grapes, shredded cheese, chopped nuts, sunflower kernels, and freeze dried mealworms. I've read that they should mostly eat chicken feed that has the appropriate amounts of nutrients they need, so they should not have too many treats. I figure that I want them to eat healthful things since we are eating their eggs. However, I realize that feeding five spoiled pets is different that feeding large flocks. They free range and I dig in the dirt so they can get worms and other insects for fun.
