Kokok Balenggek is a lesser-known chicken breed originating from the landscapes of Indonesia, particularly found in the West Sumatra region.
[1][2] It is a crowing chicken - which is a rare phenomenon where hens crow like roosters.
[3][4] The most qualitative traits of Kokok Balenggek chickens include colored plumage, a wild-type pattern, plain feathers, golden sickle feathers, yellow shank color, and a single comb.
[5] It is a long-crowing chicken breed, characterised by the unusually long-drawn-out crow of the cocks, which may in some cases last for up to 60 seconds.
