Fifty of one day-old chicks of silky fowl were hatched at Dept. of Animal Science, Gyeongsang National University and fifty of one day-old chicks of quails were hatched at Gim Hae, Gyung Nam. This experiment was investigated at 24 hours after incubation. Twee items investigated in this experiment were the live weights, the weights of head, eye-ball, brain, heart, liver, lung, kidney, stomach, small intestine, large intestine, and yolk sac. The results obtained are summarized as follows; 1, Average weights of body, head, eye-ball brain, heart, liver, lung, kidney, stomach, small intestine, large intesine and yolk sac of the quail chicks and standard errors were 6.54${pm}$0.02g, 1.38${pm}$0.l3g, 0.29${pm}$0.004g, 0.24${pm}$0.006g, 0.08${pm}$0.002g, 0.21${pm}$0.005g, 0.06${pm}$0.002g, 0.05${pm}$0. 002g, 0.46${pm}$0.010g, 0.24${pm}$0.008g, 0.10${pm}$0.004g, and 0.28${pm}$0.0l6g, respectively. 2. Average weights of body, head, eye-ball, brain, heart, liver, lung, kidney, stomach, small intestine, large intestine, and yolk sac of the silky fowl chicks and standard errors were 26.60${pm}$0.491g, 4.28${pm}$0.071g, 0.64${pm}$0.039g, 0.55${pm}$0.025g, 0.21${pm}$0.0l2g, 0.77${pm}$0.030g, 0.13${pm}$0.006g, 0.08${pm}$0.006g, 1,53${pm}$0.076g 0.73${pm}$0.036g, 0.42${pm}$0.031g, and 2.65${pm}$0.297g, respectively. 3. The relative ratios of the organ weight versus body weight in guails were compared with those of the commercial chicks (Hibro, Hubbard, and Hisex) and silky fowls. It was noted that the relative weights of the brain and eye ball with respect to body weight were larger in case of quails (Table 3). The weights of heart, liver, lung, kidney, stomach and small intestine in silky fowl were smaller than those of commercial chicks and quail chicks. Other items were similar in weight to commercial chicks ana quail chicks.
