Abstract  The purpose of this research is to compare the physical attributes of male and female KUBA chickens of their height, weight, and breast circumference to establish correlation between egg characteristics and quantitative characteristics. Such as BW, PBB, and body size. 87 KUBA hens used in the study with 40 male and 47 female. Observational experiments were recorded characteristics of the eggs, weight, perimeter, and height. T-test analysis was utilized to compare the sexes of KUBA chickens for variations in egg features, body weight, and proportionate body weight. The size vector of male and female KUBA chickens was compared using T2-Hotteling analysis. The link of KUBA chicken egg weight, egg length, and egg breadth was analyzed using regression and correlation techniques. Minitab version 21 was used as a data-processing aid. Male KUBA chickens had BW of 34.77g, PBB of 245.3g, 672.4g, 427.04g, and 210.56g at DOC, 1 month, and 2 months; female had BW of 33.41g, PBB of 239.5g, 655.3g, 206.09g, and 415.75g at the same ages. Male KUBA chickens were found with greater weight, breadth, and length, also average BW, PBB, and body sizes (P<0.05). Both male and female KUBA chickens laid eggs of a heavier weight for their larger size. Egg weight was  positively correlated with egg length (0.919). The size of male and female KUBA chickens is determined by their breast circumference, while the shape of male KUBA chickens is characterized by their breast length, and the shape of female KUBA chickens is described by their tibia length. Keywords: Egg characteristics; KUBA chicken; Quantitative characteristics   Abstrak  Tujuan dari penelitian ini adalah untuk membandingkan dan membedakan penciri ukuran ayam KUBA jantan dan betina ditinjau dari tinggi, berat, dan lingkar dada, serta untuk mengetahui korelasi antara karakteristik telur dan karakteristik kuantitatif seperti BB, PBB, dan ukuran tubuh. Ayam KUBA yang digunakan dalam penelitian sebanyak 87 ekor terdiri dari 40 ekor jantan dan 47 ekor betina. Eksperimen observasi dilakukan. Karakteristik telur, serta berat, keliling, dan tinggi, dicatat. Analisis uji-t digunakan untuk membandingkan jenis kelamin ayam KUBA untuk variasi fitur telur, bobot badan, dan bobot badan proporsional. Vektor ukuran ayam KUBA jantan dan, betina dibandingkan menggunakan analisis T2-Hoteling. Keterkaitan antara bobot telur ayam KUBA, panjang telur, dan lebar telur dianalisis menggunakan teknik regresi dan korelasi. Minitab, dalam versi 21, digunakan sebagai bantuan pemrosesan data. Ayam KUBA jantan memiliki BB 34,77g, PBB 245,3g, PBB 672,4g, PBB 427,04g, dan PBB 210,56g pada DOC, 1 bulan, dan 2 bulan; betina memiliki BB 33,41g, PBB 239,5g, PBB 655,3g, PBB 206,09g, dan PBB 415,75g pada umur yang sama. Ayam KUBA jantan ditemukan menghasilkan telur dengan bobot, lebar, dan panjang yang lebih besar, serta rata-rata BB, PBB, dan ukuran tubuh yang lebih besar (P<0.05) baik ayam KUBA jantan maupun betina bertelur dengan bobot yang lebih berat untuk ukurannya yang lebih besar. Berat telur berkorelasi paling positif dengan panjang telur (0,919). Lingkar dada digunakan untuk mencirikan ukuran ayam KUBA jantan dan betina, sedangkan panjang dada digunakan untuk mencirikan bentuk ayam KUBA jantan dan panjang tibia digunakan untuk mencirikan bentuk ayam KUBA betina.
