How do brood chicks differ from nesting ones?

Brood birds lay large enough eggs from which chicks hatch.
The chicks of brood birds are pubescent, sighted, because after 2 months spent in the egg, some organs begin to develop in the chicks. Vision is poorly developed, so they see only objects close up. Immediately after hatching, they follow the mother. Example of brood chicks: ostriches, chicks, ducklings and goslings.
Due to the short development of nesting birds, their chicks hatch naked and blind. They are helpless, immediately after hatching, they are not able to follow their mother and get food for themselves. Nestlings of nesting birds need long-term care.
