Here we have results of examination of eggs quality in two light line hybrids of chickens (Hisex Brown and Shawer 579). At the end of every four-week period an examination of external qualities of eggs was carried out. The examination was carried out on the sample of 30 eggs for each hybrid. There were total of ten examinations. The aim of these researches was to examine effects of genotype and age of hens on deformation of egg shell in 10-month period. Obtained measuring average of egg shell deformation for Shawer 579 was 26.27/1000mm and it was a little higher than deformation in Hisex Brown (25.82/1000mm). On the basis of the research, it was noticed that with the age of hen, deformation of egg shell increases, too. Higher range of variability in egg shell deformation in 4-week periods of examinations was found in Hisex, but differences were not significant. Accordingly, differences between obtained results for egg shell deformation in examined hens were very small.
