I have some 15 chicks for eggs and I´m also trying to cut down the percentage of bought grain in their fodder. I keep them in a run (approx. 30 sq meters) with deep mulch bedding (they like to scratch it very much), but I also let them forage in adjacent part of my vineyard (some 200 sq meters) and scratch worms on a compost plot from September to April. All kitchen scraps also go to them, both fresh and cooked, crushed bones included. Another part of their fodder is a dried bread, which I bring from my work. I also meet a local fish-seller on my way home, who gives me a bucket (cca 2-3 gallons) full of fresh fish offal every week. I give him some eggs as a reward. I throw them a basket full of greens (alfalfa, dandelions, clovers, common sainfoin, grass clippings..) every day from spring to autumn.. I also buy dried fish meal, made from local freshwater "weed fish" as a protein additivum. I also used "maggot dispenser" filled with some rotting offal during the summer.. During the winter, when there is only a little greens outside, I pick a scrap leaves (cabbage, cauliflower, kohlrabi) from a bin in our local supermaket. Nevertheless I buy corn, wheat and barley. Organic, if possible (not always accessible). For example, I got one bag full of barley ( 50 kg ) from my colleague who have won it in a ball raffle last winter, just for a bottle of wine (which I got from a local person as a reward for some help..). I let the grain soak and ferment for several day before giving it to chickens - this also reduce the ammount of grain in their food..
