- Evaluation of the egg breaking force of two groups of egg-laying hens throughout flock lifecycle -

Inferior quality of egg shells is the main reason for damages and losses incurred by growers of edible eggs.
Research held over the past few years evaluated the relationship between damaged eggs and specific breeds of egg-laying hens in the flock.
The observation involves a review of the shell quality and the changes it undergoes throughout the hen's lifecycle as measured by the shell's break force.
It is assumed that if correlation is found between the egg shell breaking force and the rate of eggs with broken shells in the flock, we may be able to incorporate the deterioration of the egg shell quality, as measured by the breaking force, as an additional parameter in determining the marketing age of the flock.
