easter- egger vs olive egger?

[TK Poultry]

They arent the same breed. But basically to make an olive egger (if you so choose) then you should cross some kind of green egg layer with a dark brown egg layer. To make it non-confusing that would be a sure fire way to get an olive egger. that was what I was telling you, the sure fire way to get an olive egger.

Araucana derives from collonca(rumpless/cleanfaced, a naturally blue egglayer) X Quetro (a pinkish-brown egg layer that is tailed and has ear-tufts).

Araucanas are often confused with other fowl by novice's/hatcheries


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 and rumpless also caused chick mortality.[4] 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 by the APA, conforming to the traditional style.[5] 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 are not aware of the difference.

In short, the differences are as follows:

USA & Canada Araucana – Tufts (lethal allele), rumpless, blue eggs, green legs and yellow skin (with exceptions).
US Ameraucana – Beards and muffs (NO lethal gene), with tail feathers, blue eggs, blue legs and white skin.
British, Irish, New Zealand, Asian, Japanese, Russian, Dutch, French, Spanish, Bellarus, Ukrainian, Scandinavian, Argentinian, Chilean, South African, Pacific Islands, Brazilian, Mexican, Peruvian, Arabic Nations, Indian, Pakistan, Nepalese and Australian Araucana – Beards, muffs and crest, with tail feathers, blue eggs, slate legs and grey/white skin.
Easter Egger – Variable traits.
