Cause of Dead-in-Shell in Chicken Embryo
Dead-in-shell condition of chicken embryo is due to:
- Poor ventilation
- Faulty turning of eggs
- Both poor ventilation and faulty turning — Correct Answer
- Low moisture in incubation
Explanation:
Correct Answer: Both poor ventilation and faulty turning of eggs
The Dead-in-shell condition — where the embryo fully develops but dies just before hatching — is caused by both poor ventilation AND faulty turning of eggs.
- Poor ventilation: Leads to CO₂ buildup, O₂ depletion — asphyxiation of the embryo in the final stages.
- Faulty turning: Improper or infrequent turning causes the embryo to stick to the shell membrane, preventing normal positioning for hatching.
Summary of Incubation Problems & Causes
- Early embryonic death → Too high/low temperature
- Piped egg (can't hatch) → Low moisture in hatcher
- Dead-in-shell → Poor ventilation + faulty turning
