Drawback: Costly Investment, Costly Energy Consumption
Single-stage incubation requires that the hatchery be equipped with several independent units in order to meet the needs of hatching eggs of different ages; hence an increased “cost per egg”. Although it is possible to reduce ventilation at the beginning of incubation, the total energy cost is higher as heating (during the endothermic phase) and cooling (during the exothermic phase) are performed by the machine only. In fact, this cost seems largely compensated by the sanitary advantages in hatchability rate and chick quality.
