ABSTRACT The present study was conducted to investigate the effect of hatching egg weight of broiler parent stocks on hatching results, chick performance, carcass characteristics, internal organ weights and some blood stress parameters. Eggs were divided into 3 egg weight groups (55.0 to 60.0 g (light), 60.1 to 65.0 g (medium) and 65.1 to 70.0 g (heavy)) for the experiments. After incubation, mixed-gender broiler chicks from the hatcher were placed into 27 grower pens (2x1 m) with 9 replications for 3 weight groups by using randomized block design. Each pen had 25 broiler chicks. Therefore, 225 chicks were used for each group and 675 chicks in total. The experiment was designed with nine replicates. Chi-square test, variance analysis test and Duncan...
