I haven't seen any topic about those birds. They are from Africa but here in Italy they are pretty well established. I don't know if in other part of the worlds they are known or raised, but they are pretty good birds for husbandry. Most of the time they are raised for their meat, very very rarely for the eggs. They need a covered shelter (or else they would fly away, but soem people cut part of their wings), and an outdoor area to graze. What they need to eat depends on their age. When they are pretty young forage seed will be enough, but as they grow up they will need corn and, most important, veggies and herbs, grass. Those should never be missing from their diet. And based on what I saw they are perfectly fine living with chickens.
