Egg Shape Index of Chicken Egg
The Egg Shape Index (ESI) of a chicken egg is:
- 74 — Correct Answer
- 72
- 76
- 80
Explanation:
Correct Answer: 74
The Egg Shape Index (ESI) of a standard chicken egg is 74. ESI represents the ratio of maximum width to maximum length of the egg, expressed as a percentage.
ESI Formula
ESI = (Maximum width / Maximum length) × 100
ESI of Different Poultry Species
| Species | ESI |
|---|---|
| Chicken | 74 |
| Duck | 72 |
| Japanese Quail | 78 |
Interpretation of ESI
- Higher ESI (e.g., 78–80) → more rounded egg shape.
- Lower ESI (e.g., 68–70) → more elongated egg shape.
- Ideal ESI for hatching: close to 74 for chicken (neither too round nor too elongated).
Why Other Options Are Wrong
- 72 → ESI of duck egg, not chicken.
- 76, 80 → higher than the standard chicken ESI of 74.
