Nivetha and davin

  1. 1. Life Cycle of a Chicken By Nivetha and Davin of Pri 3.9
  2. 2. Life Cycle of a Chicken Young/chick Adult/Chicken Egg
  3. 3. Stages in its Life Cycle <ul><li>The chicken has a three stage life-cycle. </li></ul><ul><li>The first stage is the egg stage. </li></ul><ul><li>The second stage is the chick stage or young stage. </li></ul><ul><li>The third or last stage is the chicken stage or adult stage. </li></ul><ul><li>The female chicken usually lays one egg a day. </li></ul><ul><li>Chicken an omnivore/eats both plants and other smaller animals. </li></ul>
  4. 4. Hatching Eggs <ul><li>A chicken needs: </li></ul><ul><li>Warmth (the chicken gives it warmth by sitting on the eggs/incubation.) </li></ul><ul><li>Food (the chick eats the egg white and egg yolk) </li></ul><ul><li>Water (the chick drinks the juice from the egg white and egg yolk) </li></ul><ul><li>It takes 21 days/3 weeks for the egg to hatch. </li></ul>
  5. 5. Inside a Chicken Egg Shell           Germinal disc Chalazae Air cell Yolk Thick Albumin
  6. 6. Inside a Chicken Egg Day 1 Day 6 Day 13 Before the egg is laid: The egg is fertilized. The fertilized egg divides and begins to grow. The cells split into groups of special function. The embryo (black dot on the egg yolk in a fertilized egg) nearly stops growing between laying and incubation ( giving warmth to the egg.) The beak becomes visible. The wing bends at the elbow. The ribs ( curved bones that are connected to the spine) begin to appear. The gizzard ( digestive system) began to form. Fingers of the wings are covered with feathers. The left and right collar bones fuse to form the bone.
  7. 7. From Egg to Chick Day 17 Day 21 The beak turns towards the air cell. The neck begins to spasm ( sudden and usually painful tightening of a muscle.) The egg tooth pips ( a series of short high sounds) through the shell. Exhausted and wet – but alive – the chick has hatched!
  8. 8. From Egg to Chick <ul><li>It takes 21 days for the egg to hatch. </li></ul><ul><li>The rooster also needs to fertilize the eggs before the egg is laid. </li></ul>
  9. 9. Hear from the EGGxperts... <ul><li>What have you learnt? What was most interesting? </li></ul><ul><li>What was challenging for you and your partner? </li></ul><ul><li>We learnt to cooperate with each other. The most interesting thing is to find information and pictures. </li></ul><ul><li>Making the calendar was the most challenging. </li></ul>
