- 6. Inside a Chicken Egg Day 1 Day 6 Day 13 The brain and nervous system begin to form. The head fold begins to form. Blood islands appear. The eyes begin to form. The beak becomes visible. The wing bends at the elbow. The allantois 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.
- 7. From Egg to Chick Day 17 Day 21 The beak turns towards the air cell. The neck begins to spasm. The egg tooth pips through the shell. Exhausted and wet - but alive - the chick has hatched!
