I’m a first time chicken mom. My chickens are about 3 1/2 months old. They are growing and doing well. I’ve watched a lot of videos about feeding them scraps and greens, phasing out commercial feed. Every day they get salad greens that I get from the food bank. I also feed them kitchen scraps. I cooked up some turkey bones, separated the meat and cooked with rice. Is that wrong? They don’t eat as much chicken feed when they have the extra. I want them to be healthy. Thank you.
Rice is non-nutritious, especially white rice. So are many salad greens, an exception being romaine lettuce. I would avoid feeding any rice, unless it's at least brown rice, which does have some nutrition, and avoid most of the salad greens except romaine, kale, chard, dandelion, parsley or spinach. Chicken feed purchased in 40# bags is very economical, and gives them what they need. 10% treats (scraps) is fine, and if they can free-range they'll also get grubs and beetles, which are high in protein. Oatmeal is commonly cited as good for chickens, but chickens can't utilize the protein in it, so it should be a treat only. Beets, tomatoes, marigold and nasturtium flowers, apples, pears, cherries, strawberries--all good, if no mold. Yoghurt, cottage cheese, and leftover milk are okay. My girls love cooked (fresh, not spoiled) fish. Especially if they are doing the taxing work of laying eggs, I'd stick to a base of commercial food and free-feed oyster shell. Without the commercial food, make certain to provide oyster shell for calcium, and they also need grit for their gizzard if they're getting anything other than commercial feed. (If they free-range, they can pick up grit.) They can stay alive and even produce eggs on a scrap diet, but they won't be terribly healthy.
