Paragraph 11

All automatic and mechanical equipment essential for the health and welfare of the laying hens shall be thoroughly inspected at least once daily. Where defects are discovered these must be rectified immediately or, if this is impracticable, appropriate steps taken to safeguard the health and welfare of the laying hens until the defect has been rectified. Alternative ways of feeding and of maintaining a satisfactory environment must be available for use in the event of a breakdown.

There shall be an alarm system to warn the stock-keeper of failure of any essential automated ventilation equipment.
