My goodness, what a fuss! Australian chickens must be much tougher. My girls get whatever scraps might be available, ranging from pizza (rarely any of that left over), sausages and any other meat including salami, mice caught in traps, fruit of every kind, especially water melon, but not citrus because they just don't like it, veggies except onion because they don't like it, and avocados (not good for them). Of course they have their layer pellets on free feeding, and I have never had any digestive problems with any of this food. In rural areas in Australia, there is a native plant called a bush tomato, and when my girls are allowed out for a free range roam, they make a beeline for the little red and yellow fruits on the bush tomatoes, with no ill effects.
