The study was fulfillment to examine variations among two native breeds (Dandarawi and Fayoumi), local synthesized strain (Norfa) and commercial laying strain (Hy-Line) for eggshell quality using different external measurements, various instruments (quasi-static and mechanical properties) and using Scanning Electron Microscope (SEM) technique. In this experiment, growth related traits (i.e. body weight throughout rearing stage, the age and body measurements at sexual maturity), egg production traits (number and weight), internal and external egg quality traits during different phases of production were also investigated.
