Nicobar megapode may be used by more than one pair of birds. Microbial activity is the primary source of heat within mounds for incubation. The incubation period is approximately 70–80 days varying based on the incubation temperature. The young birds hatch fully feathered, and as soon as the feathers dry up, can fly. They do not need any parental care and join the group immediately. In the 1900s, eggs taken to Calcutta zoo hatched and the chicks, reared on a diet of termites, grew very tame.

Micronesian megapode the multiple threats across its range, it is likely to be suffering from a continuing decline. It seems that the only way for the species to be safe is to protect a few small islands and release a small population of megapodes there. That way, a safe population is secured. On the larger and higher islands, an increase of people and introduced pests will sooner or later destroy any megapode populations. The Marianas Island megapode or "Megapodius laperouse laperouse" is the nominate subspecies of the Micronesian megapode found in the Mariana Islands. It is rare, localised and in danger of
