Large breeds such as Orpingtons, or Wyandottes should have half as much space again. Your chicken coop should have: 1  Floor Space: A minimum of 30 cm x 30cm (90 square cm) per bird floor area. i.e. If you have a coop that is 90cm x 90cm, this could house a maximum of 9 medium chickens. 2  Do not include nest boxes in this measurement. 3  This should be the inside floor area.
