Chick Embryo Development Stages: From Egg to Hatching

Chick Embryo Development Day 0: Fertilization → zygote → blastoderm formation Day 1: Cleavage → primitive streak → early nervous system Day 2: Heart starts beating → blood vessels → head & eye formation Day 3: Limb buds appear → beak formation starts → organogenesis begins Day 4: Eye pigmentation → wing & leg differentiation Day 5–6: Feather germs → claws & digits visible → slight movement Day 7–10: Skeleton ossification → organ development → rapid growth Day 11–14: Major organ maturation → embr

Chick embryo development spans about 21 days, progressing from microscopic cell division (cleavage) and germ layer formation (gastrulation) to rapid organ development (organogenesis) where the heart forms, limbs appear, and features like eyes, beak, and feathers develop, culminating in the chick orienting for hatching and breathing air by day 20-21, as detailed in daily milestones from early cell clusters to a fully formed chick ready to pip the shell.
