But presumably a hen can get out through a 25cm gap, because it if couldn't the Higgins wouldn't have built the shed that way.

These are sophisticated, technology reliant businesses representing a huge investment.
The Higginses made the move to free range egg production before the new Code of Animal Welfare (Layer Hens) was released in December by the Minister for Primary Industries.
Their direction and energy would be applauded by New Zealanders.
Their business has a tick from the SPCA for meeting animal welfare concerns and is planning expansion. It would be a shame if such a forward-looking enterprise is penalised for a building that already has the endorsement of New Zealand's major animal welfare watchdog.-->-->
