For cage or pen construction, 7 mm square welded wire mesh is recommended to provide secure footing, prevent leg injuries and prevent chicks escaping through side walls.
Adult quail will live and produce successfully if they are allowed 145 cm2 of floor space per bird (125 cm2 per bird on wire floors). Often, in community pens, they will not build a nest but will hide their eggs in the litter. For this reason quail egg producers usually prefer to house their birds in cages. A cage 13 × 20 cm is large enough for two birds. The cage should have a solid metal or plywood roof to minimise head injuries if the birds take fright.
