The ancestors of the modern Araucana chicken were purportedly first bred by the Arauca Indians of Chile -- hence the name "Araucana." The Araucana as we know it today is a hybrid of two South American breeds: the Collonca (a naturally blue-egg laying, rumpless, clean-faced chicken) and the Quetros (a pinkish-brown egg layer that is tailed and has ear-tufts).

The current North American standard calls for a chicken that is rumpless (missing their last vertabrae and lacking a tail), possesses ear-tufts (feathers that grow out from near the birds' ears), and lays blue eggs. Some European standards call for muffs and beards on Araucanas, and/or recognize a tailed version of the breed. In the United States and Canada, however, muffs, beards, and tails are all disqualifications.

Araucanas are often confused with two other types of colored-egg-laying chickens: Ameraucanas and Easter Eggers. An Easter Egger or Easter Egg chicken is any chicken that possesses the blue egg gene, but doesnt fully meet any breed descriptions as defined in the American Poultry Association (APA) and/or the American Bantam Association (ABA) standards. ...

The Ameraucana should also lay blue eggs, but unlike the Araucana it has a tail and possesses muffs and a beard, which are quite different from the tufts of the Araucana. Muffs and beards are fluffy poofs that grow on the cheeks and chin of the bird, whereas tufts are actual feathers that grow from fleshy lobes called peduncles on either side of the birds' face. Tufts are associated with a lethal gene, which makes them difficult to attain.

The Easter Egg Chicken is not an actual breed; the term refers to any bird that lays colored eggs. The vast majority of birds sold as "Araucanas" or "Ameraucanas" are actually neither. Instead, they are mixed breeds with no APA (American Poultry Association) Standard that lay colored eggs, ranging from bluish and greenish to pinkish-brown, and sometimes even tan, gray or white.

The Araucana's eggs are not more nutritious than eggs of other colors (despite popular myth), but the birds are reliable layers of medium-sized eggs. The Araucana, if hand-raised specifically, is extremely well-tempered, calm and trusting.

Controversy on Origins

There has long been debate whether araucanas were bred from chickens brought by Europeans to South America after Columbus or rather arose from chickens brought directly over the Pacific Ocean from someplace nearer to all chickens' presumed ancestral home in Southeast Asia. If, as sometimes claimed, auracanas predate the Europeans in South America, their presence implies pre-Columbian trans-Pacific contacts between Asia and South America. A direct Asian, non-European, but not necessarily pre-Columbian origin has received some support in a recent study of modern araucanas' mitochondrial DNA. However, the authors of the study have stressed that to establish that araucanas are indeed a breed developed in pre-Columbian South America would require analyzing apparent chicken remains from a pre-Columbian site. (J. Gongora, et al., "Mitochondrial DNA sequences reveal a putative East Asian ancestry for old Chilean chickens," Proceedings of the International Conference on Animal Genetics, ISAG 2006, Porto Seguro, BA, Brasil.)

Now (June 2007), researchers led by Alice Storey at the University of Auckland, New Zealand, report finding evidence that may ruffle some scholarly feathers. They found chicken bones of Polynesian origin at a site in what is now Chile. Radiocarbon dating of chicken bones at the site on the Arauco Peninsula in south central Chile indicated a range of A.D. 1321 to 1407, well before the Spanish arrival in the Americas. The researchers were able to obtain DNA from some of the bones of these early birds, and found they were identical to ancient chicken bones previously found in Tonga and Samoa. Chicken had been used in the Pacific for at least 3,000 years, spreading eastward across the region as Polynesians gradually populated the islands. The DNA from these chickens also shared some unique sequences with modern Araucana chickens from South America and some current chicken types in Hawaii and Southeast Asia, the researchers found. http://news.yahoo.com/s/ap/20070604/ap_on_sc/fowl_finding250 (Study: Chickens beat Columbus to America)

Recognized breeds

The APA Araucana belong to the following Poultry Class AOSB "All Other Standard Breed " while the ABA belongs to the following class "All Other Comb Clean Leg". In Great Britain, the PCGB (Poultry Club of Great Britain) classifies it as Light, Soft Feather.

The colours recognized by the APA/ABA/PCGB are :

The APA recognizes 5 colours "Black , White , Black Breasted Red , Silver Duckwing , Golden Duckwing "

The ABA recognizes 6 colours " Black , White , Black Breasted Red , Blue , Buff , Silver"

The PCGB recognizes 12 colours " Lavender, Blue, Black/Red, Silver Duckwing, Golden Duckwing, Blue/Red, Pyle, Crele, Spangled, Cuckoo, Black and White.

Araucana, Ameraucana or Easter Egger?

When the Araucana was first introduced to breeders worldwide, in the mid-20th century, it was quickly realized that the genetics that produced tufts also caused chick mortality. As it turns out, two copies of the gene causes nearly 100% mortality shortly before hatching. One copy causes about 20% mortality. The tufted gene is dominant however. Because no living araucana possesses two copies of the tufted gene, breeding any two tufted birds leads to half of the resulting brood being tufted with one copy of the gene, a quarter being clean faced with no copy of the gene, and a quarter of the brood dead in the shell having received two copies of the gene.

In the decades to follow, most breeders took one of two tactics - either to preserve the old style of bird, or to breed out the tufts while increasing productivity.

In 1976, the first standards for the breed were accepted, conforming to the traditional style. This was followed, in 1984, by a second standard for the "improved" variety.

The gene for blue eggs is dominant, so the term "Easter Egger" is used to describe birds of mixed breeding that produce such eggs. Unfortunately, these mixed breeds are often incorrectly labeled as Araucanas or Ameraucanas, and marketed to backyard poultry hobbyists who aren't aware of the difference.

In short, the differences (according to the APA/ABA standards) are as follows:

Araucana - Tufts (lethal allele), rumpless, blue eggs, green legs and yellow skin (with exceptions).

Ameraucana - Beards and muffs (NO lethal gene), with tail feathers, blue eggs, blue legs and white skin.

Easter Egger - Variable traits.
