Research variables were the weight of eggs, interior and exterior quality of eggs. 780 eggs from two groups of 45 quails per genotype, collected and stored during 13 days, were used. The tests used in our study were the Student’s t-test, the ANOVA and the post-ANOVA tests. The results carried out a significant difference among the different genotypes concerning the external eggs quality (P&lt;0.001).  The wild-type quails got the high average concerning the length, the width and conformation rate than yellow quails. Moreover, these quails recorded also high weight than the others. The same result was recorded for final weight average.</p><p>The eggs of quails of wild-type feather showed out better mean such as 79.87 %, 31.55 mm and 25.16 mm for respectively conformation rate, the length and the width. Eggs weight was affected by quail feather color. Thus, the eggs of females with wild-type feathers carried out the high weight (10.75 g vs 10.53 g). Otherwise, the color of feather doesn’t occur any effect (P&gt;0.05) onto weight loss. However, there is no significant effect (P&gt;0.05) for internal quality of eggs. Concerning storage duration, it affected significantly the parameters of internal quality of eggs (P&lt;0.001) such as height of egg yolk, height of white, egg yolk’s diameter, albumen and yolk index, Haugh unit. The best parameters were recorded from eggs storaged between 1 and 5 days. In the same way, eggs loss weight was significantly affected by storage time which ranged from -0.06 g to - 0.22 g. Relation between storage duration and color of feather affected significantly the level of eggs albumen.</p> ER -
