Cassowary need to be housed by themselves in large planted and shaded enclosures(shade is because they live in dense rainforests), but several can be kept together if the pen is a good size and it is plated so they don’t see each other. Females don’t like to be housed together. They are hardy to cold temperatures outside and only need a sheltered area that’s heated in extreme cold. Their diet is mainly fruit and the pen should be planted with fruiting plants that they can forage on as a supplement to their main diet. There’s more diet stuff but I haven’t really checked it out. Chicks are notoriously hard to raise- it seems that many eggs are also infertile
