Shengrong and mindy 3.9

  1. 1. Life Cycle of a Chicken By Mindy and Sheng Rong of Pri 3.9
  2. 2. Stages in its Life Cycle
  3. 3. Hatching Eggs <ul><li>The embryo needs air, food and water to grow, so thin red blood vessels spread out from it over the yolk and then round the inside of the shell . The yolk provides most of the food and the albumen provides more protein and water .The oxygen passes through the shell and the membranes. The chick inside the egg begins to breathe with lungs after poking a hole into the air space. </li></ul>
  4. 4. Inside a Chicken Egg       AIR CELL   SHELL GERMINA DISC CHALAZA YOLK THICK ALBUMIN
  5. 5. Inside a Chicken Egg Day 1 Day 6 Day 13 The egg is fertilized. The zygote divides and begins to grow. The cells segregate into groups of specialized function. The embryo nearly stops growing between laying and incubation. The beak becomes visible. The wing bends at the elbow. The allanto is begins to fuse with the chorion. The ribs begin to appear The gizzard begins to form. The intestines begin to loop. Fingers of the wings are covered with feather papillae. The left and right collar bones fuse to form the wishbone.
  6. 6. From Egg to Chick Day 17 Day 21 The beak turns towards the air cell. Exhausted ,wet and alive. The chick has hatched!
  7. 7. 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>I have learnt to cooperate with my partner. </li></ul><ul><li>We learnt more about chickens.
