answer:It depends entirely on the requirements of the egg, the parental behaviour selected for in the adult exhibiting the care, and the capacity of the adult to provide sufficient and appropriate resources for the young. Scrub turkeys in Australia place their eggs in giant mounds of earth, which hatch, excavate their way out, and immediate forage on their own with zero input from the adult. ie. there is no further parental care. The young of most (I would imagine all) other bird species would not survive such circumstances. Basically some avian parents have such unique behaviours, morphologies, etc.. that there won’t be other species that can be raised by them.
