In animal characterization research it is essential to establish ranges of typical and fluctuating behaviours of its variables and parameters. For this, the use of robust statistical inferences constitutes a relevant tool. Thus, the study of body traits in a rustic dual-purpose avian population was approached, through correlation and principal component analysis (PCA), contributing to its morphometric characterization and verifying the usefulness of the statistical methods used in a small group. In total, 52 chickens (males and females) were evaluated, classified as adults and older adults, analysing a series of quantitative traits. An association was found between live weight and skull width, middle finger length, wing length (p < 0.01), back length, keel length, breast width, beak length and tarsus length (p<0.05), in adult males, while for older birds calculations are suggested ...
