Eggs were characterized by some physical and geometrical properties such as mass, length, width, eggshell thickness, geometric mean diameter, surface area, sphericity, volume, and eggshell radii of curvature. Egg samples were compressed along axis of their symmetry (X axis) and perpendicularly to this axis (Z axis). Four different compression rates were used as: 0.0166, 0.166, 1.666 and 5 mm/s. The highest rupture force, deformation at the egg’s rupture and energy absorbed up to the fracture were found when Japanese quail eggs were loaded along their X-axis. The rupture force increased with the compression (loading) rate. The rate sensitivity of the eggshell rupture force was closed to that observed for the hen’s eggs.
