[2] The Jærhøns was selectively bred at the state-controlled breeding station at Bryne in Jæren from its establishment in 1916 until it closed in 1973.

Breeding stock was then transferred to the state agricultural college at Hvam, Nes.

[6][9] The Jærhøns was listed as a "conservation-worthy national breed" by the Norwegian Forest and Landscape Institute in its 2008–2010 action plan for the conservation and sustainable use of animal genetic resources in Norway.

[8] The Jærhøns lays approximately 215 eggs per year,[6] about 20% less than industrial purpose-bred layers.

The eggs are white, and weigh a minimum of 55 g.[2] This poultry article is a stub.
