Relationship Between Shell and Shell Membrane Strength and Other Egg Shell Characteristics

There was a significant difference in the shell strength of chicken eggs with different curvatures of the large end. Holding temperatures of eggs significantly influenced shell strength but not shell membrane strength. There was a significant negative correlation in chicken eggs between shell strength and membrane strength in small and medium curvature groups but not in the large curvature group. Shell strength was positively correlated with shell thickness. A positive correlation was found in turkey eggs between membrane strength and length-width ratio and between shell strength and shell thickness.
