Acclimatising Wall
A weld mesh door which is fitted behind the removable wall opposite the nest bank, which, although it is removable for cleaning, would normally stay fitted. When you wish to harden off young birds you simply remove the external board wall to reveal the weld mesh and your stock stays in the ark. The side wall goes back over the wire at night so at no time do quick agile chicks get a chance to 'make a break for it'.
