    Division and growth of living cells
    Segregation of cells into groups of special function
    BETWEEN LAYING AND INCUBATION
    No growth; stage of inactive embryonic life
    DURING INCUBATION
    FIRST DAY:
    16 hours - First sign of resemblance to a chick embryo
    18 hours - Appearance of alimentary tract
    20 hours - Appearance of vertebral column

    22 hours - Beginning of formation of head
    23 hours - Appearance of blood islands - vitelline circulation
    24 hours - Beginning of formation of eye
    SECOND DAY:
    23 hours - Beginning of formation of heart
    35 hours - Beginning of formation of ear

    Embryo turns its head toward the blunt end of egg
    SIXTEENTH DAY:
    Scales, claws, and beak becoming firm and horny
    SEVENTEENTH DAY:
    Beak turns toward air cell
    NINETEENTH DAY:
    Yolk sac begins to enter body cavity
    TWENTIETH DAY:
    Yolk sac completely drawn into body cavity; embryo occupies practically all the space within the egg except the air cell

    That is really amazing. I can't believe a little chick can grow from nothing to a little fuzzy thing in 21 days. Thanks
