The experimental groups were the first group without injection and the second, third and fourth groups injected with 0.1, 0.2, and 0.3 from aqueous extract of annatto seeds into the amniotic sac. The results showed, significant increase for T₄ in hatching ratio, significant increase in embryo mortality for T₁ compared other groups, the T₂ and T₃ was the heights significantly in chicks weight at hatching and 12 hours after hatching, while the in ova injection groups was the best in glycogen level in the breast muscle, liver and heart.
