Hatching Quails. Quail eggs do not need to be incubated as long as other poultry, Japanese Quail need between 16-18 days of incubation. Japanese Quails rarely sit on their eggs, an instinct they have almost lost by intensive breeding. An incubator is required to hatch the eggs.ggs set for incubation should be 3 to 7 days old; older eggs will have a lower hatch rate and need a longer period of time to hatch. Before incubating eggs, store at room temperature and turn the eggs everyday. Ensure you only use clean eggs, dont wipe eggs with anything i.e. liquids.
