    • Life Cycle of a Chicken By Sing Yee and Zheng Yu of Pri 3.9
    • Stages in its Life Cycle
      • There are three stages in a life cycle of a chicken.
      • The egg comes first, followed by
      • the chick. After the chick, it is the
      • hen/rooster.
    • Hatching Eggs
      • To hatch eggs, the egg must be fertilised. That means, the hen and rooster have to mate to have a fertilised egg. The temperature must be right. It has to be maintained at 37 celsius (degrees).

      • Mission #4
      Day 17 Day 21 The beak turns towards the air cell. The chick hatches.
    • From Egg to Chick
      • The body parts develops, day after day. Soon, the chick is ready to be hatched. It forms a hole and make it bigger. Slowly, it pushes itself through it.
    • Hear from the EGGxperts...
      • I learnt how a chick develops into a chicken. It takes 21 days to hatch. The most interesting part of all was doing the calendar. The most challenging part was when finding pictures of the life cycle of a chicken.
