This experiment was conducted to determine the phenotypic characteristics, growth rate, carcass yield and egg performance of Betong Chickens (BC). One Hundred and ten dead of 8-52 weeks old birds were raised in all-litter pen. Body weight at maturity of male and female were within range of 2.11+-0.28 (50)-2.35+-0.19(50) and 1.69+-0.23(50)-1.78+-0.23(50) kg. It was also found that the body shape at the age interval 8-16 weeks was greater than the other age interval of BC. Prechilled carcass weight of male and female were 82.07 and 78.77 percent, respectively. The age at the first egg of chicken was 23 week, whereas No. Of egg production, egg weight at onset of first egg, egg weight, egg yolk color and egg shell thickness were 13+-4.50(20) egg/clutch, 38.50+-0.23(20) and 47.77+-3.37(20) g/egg, 9.53+-1.16(20) and 0.3+-0.03(20) mm, respectively. The chicks down are whitish-yellow color. Slow feather appeared during 0-4 weeks of age with few primary and secondary feathers, which are narrower and shorter than those of the other native varieties. When the Betong chicken is an adult, only 4-8 secondary wing feathers have developed, and the tail feathers are short. In adult the plumage of males are reddish-yellow while the females are whitish-yellow. The skin color is yellower than other Thai native chickens. The comb is single type.
