Abstract
The first experiment resulted that junglefowl naturally bred had significantly higher egg numbers than artificial insemination (p < 0.05), with an average of 34.29 ± 16.87 and 20.00 ± 5.41, respectively. Regarding the number of fertile eggs, it was found that the natural method was significantly lower than artificial insemination (p < 0.05) with an average of 12.94 ± 1.36 and 34.50 ± 12.04 eggs, respectively. The second experiment showed that hatching by natural method, which the hens incubated the eggs in the nest, the hatching rate was 78.57 ± 13.47%. Moreover, the eggs hatched in the incubator had the hatching rate of 67.43 ± 8.15%, of which, both methods had not statistically differed (p > 0.05). However, hatching in an incubator was better than orther methods as it shortened the incubation time of the laying hens. Consequently, it resulted in hens to be able to lay more eggs than hens that hatched naturally.
