Absolute weight gains (AG) during the first 7 d of rearing were negatively
affected by storage and age of breeders. However, the effect of storage was more obvious in
chicks from eggs of younger breeders. Field reports indicate that chick weights during the first
2 wk of rearing were lower for chicks from eggs of younger hens but were not affected by the
storage time. At the end of the third week, chicks from fresh eggs were heavier than those from
eggs stored for 7 d, and this difference increased until 42 d. During the same period, age of
hens did not affect broiler weights
