The aim of this study was to investigate the correlation of keeping the laying hens on the basic physical parameters of egg quality (egg mass, part of the individual parts, shape index, shell thickness, egg yolk color, pH value of egg yolk and egg white) and mechanical properties (by determining the force of the fracture). For the purpose of research, eggs from hybrid Hissex Brown laying hens where collected from different systems (enriched cages, aviaries, free range). It was found that chickens kept in enriched cages, compared to those held in aviaries have significantly higher egg mass. The thickness of the shell was similar to that of eggs from all of above mentioned holding systems or we can also say there was no statistically significant difference between the treatments. The proportion of shell was statistically higher in eggs from enriched, while the share of egg yolk was statistically higher in the eggs from free range. The share of egg white at eggs from aviaries was higher compared to eggs from all other holding system. Significantly higher value of L* and significantly lower value a* for egg colour from free range system compared to all other systems for laying hens was detected. Given the statistically significant differences shown, we can conclude that the system of laying hens of chickens significantly influences the basic physical properties of the eggs, but it is difficult to say which of these holding system would be the most favourable, given that the perception of "egg quality" depends on personal preference both breeders and consumers themselves. Based on our results we can conclude that forces didn't change based on system of keeping chickens, what means forces are the same at every system, weakest over side, and strongest on top and bottom of egg.
