Observation of the physical quality of the quail eggs resulting from the crossing is very important to get the maximum physical egg quality data. This research was conducted to determine the exterior quality of brown and black Japanese quail eggs from first generation (F1). One hundred Japanese quails were divided into four types of lines as treatments: Black 1 (L1), Brown 1 (B1), Black 2 (L2), and Brown 2 (B2). Each treatment consists of 25 quails as replication. Egg retrieval for exterior and interior quality testing when quail was 14 weeks old. Eggs were taken every day for three days then physical eggs are tested. Egg physical quality testing was carried out every day for three days. This study used a Completely Randomized Design (CRD). The data observed in this study was the egg weight, egg length, egg width, cavity height, eggshell weight, eggshell thickness, and egg index. In addition, the data was analyzed using analysis of variance, and pairwise differences among quail lines were conducted using Duncans multiple range test (DMRT). The results showed the egg weight and egg widht was significantly different among lines (P<0.01) and four types of line was not significant (P>0.05) on the egg length, cavity height, eggshell weight, eggshell thickness and egg index. It can be concluded that crosses of black quail male and brown females had the highest egg weight and egg width compared to crosses of brown quail male and black females.
