Egg Position in Setter and Hatcher
Position of egg in setter (1st 18 days of incubation) & hatcher (last 3 days of incubation) are respectively:
- Upright & Horizontal — Correct Answer
- Horizontal & Upright
- Horizontal & Horizontal
- None of these
Explanation:
Correct Answer: Upright & Horizontal
Egg position in the incubator is critical for proper embryo development:
- Setter (first 18 days): Eggs placed in upright position — broad end upward. This keeps the air cell (at the broad end) at the top, helping the embryo develop with head positioned toward the air cell.
- Hatcher (last 3 days): Eggs placed in horizontal position — allows the chick to pip (crack the shell) and hatch freely without rotation constraint.
Why This Matters
- The air cell at the broad end has maximum pores for gaseous exchange.
- Head of the embryo forms toward the broad end.
- Horizontal position in hatcher allows the chick to rotate and pip correctly.
