Average chick hatching weight was higher from eggs of older breeders (Table 3). Body weights up to the first 14 d of rearing were higher for birds from eggs of older hens (P < 0.05). However, from the end of 14th day of rearing to the 21st day, broilers from younger breeders showed greater growth rate than those from older breeders such that body weights at 21 d were similar between both groups and remained statistically the same until 42 d of age. As in experiment 1, only weights of 1- d-old chicks were not significantly correlated with weights of 42-d-old broilers.
