Barn
The barn system has a series of perches and feeders at different levels. The maximum stocking density is 9 birds per square metre and there must be at least 250cm square of litter area/bird. Perches for the birds must be installed to allow 15 cm of perch per hen. There must be at least 10cm of feeder/bird and at least one drinker/10 birds. There must be one nest for every 7 birds or 1 square metre of nest space for every 120 birds. Water and feeding troughs are raised so that the food is not scattered

Free range
In free-range systems, the birds are housed as described in the barn system above. In addition birds must have continuous daytime access to open runs which are mainly covered with vegetation and with a maximum stocking density of 2,500 birds per hectare.

A hectare is 10,000 square metres = 2.471 acres
