How long do you think humans have been managing avian breeding?
Study of Cassowary eggshells from 2 sites in New Guinea suggests the Late Pleistocene people may have been harvesting late-developed eggs. Either to eat the embryo chicks or intentionally hatching them, some 18,000 years ago. Well before the known domestication of chickens and geese.
Cassowaries are classed as ratites; flightless birds without a keel bone.
Their wild diet primarily consists of fruits and seeds, but they will take insects and small vertebrates if they wander past. With the availability of specialist diets they are well catered for. If not out on range they need soluble grit.
Generally, a high proportion of fruit is not good for kept birds: high sugar content and low fibre can be a problem. Starch in bread can also lead to gut issues so is best avoided.
