It may occur in chicks that are packed without enough air ventilation holes or spaces, or when birds are moved to new quarters or when they are frightened. It is more common at night.

Causes of Smothering
Smothering is caused by crowding into a corner or pilling. It may occur when birds are moved to new quarters, when they are frightened by a loud noise or intruder in the house, or when birds are chilled. It is often more common at night. Smothering or chicks in boxes occurs due to over crowding or when boxes are stacked too high, or there are insufficient air ventilation holes.
Effects of Smothering
Sudden death of birds in one area of the house (usually in one corner) without any other signs is indicative that death has occurred by Smothering.
