The lack of effect of storage on hatchability in young broiler breeders compared with older breeder sinth is study is consistent with previous reports [5, 7, 30]. Lapa ˜o et al. [7], however, found differential hatchability in young breeder eggs. Hatchability of fresh eggs from older breeders was as good as that of young hens but declined significantly with storage probably as a result of the lower quality of the albumen. Because there was no effect of storage on young hens’ eggs, the data affirm an earlier suggestion by Kirk et al. [30] and Meijerh of [31] that eggs of young breeders can be stored instead of those of older breeders. Chick quality showed higher percentage of high score chicks from young breeders with little effect of storage. Older breeders produced lower percentage of high quality chicks with a significant effect of age × storage. To our knowledge, this is a first report on the effect of age × storage on quality of chicks .The lack of effect of storage alone in young hens compared with older hens suggests, again, the involvement of differential age-related effects. The finding that storage had no effect on 1-d-old chick weights is in agreement with a previous report by Reis et al. [5]. O’Sullivan et al. [32] reported that the weights of 18-d embryos increased with parental age. The heavier embryos and chicks from older breeders have been attributed to heavier incubating egg weights at setting. The lack of correlation between quality score and 1-d-old weight emphasizes that both are different and independent parameters and that high weight at 1 d of age may not necessarily mean good quality as further substantiated by the growth performance of the chicks. The depressive effect of egg storage on body weight at 7 d was greater in young breeders, apparently due to lower daily weight gains .Even though broilers from older birds had higher weightsat1-dofage,weights at 7 d were similar for chicks from fresh eggs of both age groups, main lydue to greater body weight gains per day
