Turning Angle of Eggs in Incubator
Turning of egg in the incubator should be at:
- 45° vice-versa — Correct Answer
- 90° vice-versa
- 60° vice-versa
- None of these
Explanation:
Correct Answer: 45° vice-versa
Eggs in the incubator setter should be turned at an angle of 45° in both directions (alternating back and forth) for optimal hatchability.
Turning Details
- Angle: 45° vice-versa (alternating)
- Frequency: At least 8 times per day
- Duration: During first 18 days only (not in the hatcher for the last 3 days)
- Purpose: Prevents the embryo from sticking to the shell membrane
Modern commercial incubators use automatic turning mechanisms. Manual turning should be done an odd number of times per day so the egg is not in the same position on consecutive nights, which is the most sensitive period for embryo development.
