To evaluate the effect of egg weight on some productive and reproductive as age and weight at puberty Japanese quail birds . A total of 400 eggs were collected and were categorised into 4 weight groups as (10 ,11 ,12,13 g) . The result showed that the chick weight significant (p < 0.05) increase for birds of fourth group as well as weight increase for its birds at fourth week of age compared with weight of first group birds. The results shows early age of sexual puberty for males and females of (second , third and fourth ) groups compared with the males and females of first group. There were a significant (p < 0.05) increase of females weight in fourth group at the age of sexual puberty compared with other groups. The results shows a significant (p < 0.05) increase in weight of first egg product from females of second , third and fourth groups compared with the weight of first egg product from females of first group. In conclusion, heavy sized eggs (13g) lead to better quality of day-old chicks with better post hatching performance.
