The first step in chicken breeding is the production of chicks, which requires a high-performance incubator. In this research, the performance of two incubators was compared. One of them was instrumented with a hybrid system based on fuzzy controller (HIFC), another one was the commercial incubator (ON/OFF). By comparing the important parameters to make suitable conditions for eggs hatchery, the percentage of eggs hatching, egg weight changes, chick’s hatch time and energy consumption were compared and evaluated. The result showed that the eggs hatching ratio was 92.13% for HIFC and 78.16% for ON/OFF systems. The HIFC system showed a better result in controlling egg environmental conditions than the ON/OFF system, based on eggs weight changes and chick’s hatch time. The energy consumption of the fuzzy controller was 31.25% less than the ON/OFF controller. The amount of energy received by the solar hybrid system over a 21 day periods was 27.20 kWh. For the HIFC system, the amount of energy needed for a hatching period was 24.24 kWh which shows an excess energy of 12.21%. For the ON/OFF system, contribution of solar hybrid system for power requirement was 77%.
