Biometrical value of the measured constants, namely, the mean value(M),the standard deviasion (σ) and the normal type (M ±σ） were caluculated(Table 1). (3)The measured characters of body No.14 which won first prize were “M～M＋σﾞ”in biometrical value. Those of N0.12,N0.32 and N0.46 fitted into the nomaltype(M ±σ). From these results it may be concluded that the body characteristics of symmetrical hens are found to agree with the normal type.
