... what actually makes a bird fit into each of these classes. i know EE like pele said is a slurry class where you just throw everything in there if it produces a green egg or no. Please help me to understand the diffrences. Also im kinda noticing from 1 hatchery web site to another the ameraucanas look different in color and patterns. if hatcherys arnt that uniform in what they produce how can we have the ameraucana and EE classification anyway. It seems like its just left up to us to argue about and there is no clear definition. even if a breeder says this is 100% arucana blood people will argue defects in the standard make it a different bird. Which doesnt make since to me. it should still be an arucana that just isnt perfect right blood line is bloodline. how can a defect in the norm pattern call it something else.
I am sure I will get flamed for this response by some as passions run deep here.
I suggest you go back to the link to the Ameraucana History
http://www.ameraucana.org/history.html and read the information there. What happened is there was a lot of people breeding for egg color--Easter Egg birds (some called them Ameraucanas and some called them Araucanas)-- since the 1920's discovery of a blue egg laying type of chicken in South America. There were a mishmash of traits including rumpless, tufted and beard and muffed birds. Private folks as well as Hatcheries were breeding them. In the 70's the first group to break off and standardize was the Araucana folk with a breed standard for tufts and rumpless birds. Then some folks worked very hard to try to get a breed standard for Muffed and Bearded blue egg layers. The Standard for Amaraucana was set and any bird that didn't meet the standard was officially not an Ameraucana. So now the Hatcheries (who have never been know to breed to standard, but rather for production) have their flocks they have been calling Ameraucanas for years and they all the sudden don't match breed standard so they are officially not Ameraucanas. The Hatcheries don't show their breeds and so they don't really care and continue to call their chickens something that they are officially not, much to the dismay of the Ameraucana breeders and folks that think they are getting a true Ameraucana bred to the standard.
Now the waters are muddied about what is considered pure or not and much of it depends on the culture of the groups involved. Apparently the Araucana folks are a little more lenient about birds that don't meet breed standards and are willing to accept birds that are not show quality and at least call them non-standard Araucanas. The Ameraucana folks are resolute that no chicken, even if it is from purebred parents, be called an Ameraucana if is not up to standard. Those birds are automatically labeled EE. The bird may be genetically from a line of pure Ameraucanas but because it has the wrong plumage or leg color it is labeled as EE. Now to make matters worse, any bird with a hint of green legs or a beard or muffs is called an Easter Egger even if is has no Ameraucana genes in its body. So the term Easter Egger has now expanded to include possibly pure but off-type Ameraucanas (accidental breeding of two different colors resulting in a clutch with non-standard colors but genetically from pure Ameraucanas) to any bird that has a hint (or not) of beard of muffs and has kind of become a catch-all for a mutt chicken with some qualities that might be Ameraucana. Hence your confusion.
I pass no judgement one way or another--it's each breed standards decision to be as lenient or strict as they want to be. Many breeds have decided what their standards are and they may change over time as it is somewhat political. A case in point is with Quarter Horses. When they formed the standard they DQ'd as unregisterable any horse that had white above the knee or hock but would accept horses from the Jocky Club (thoroughbreds) so a foal from registered Quarter Horses was not considered a purebred Quarter Horse but a half QH/half TB was. The Paint folks said they would gladly register those horses and accepted them. Sometime in the 90's the Quarter Horse folks realized they were losing some really awesome genetics (and expensive high value horses so I am sure there was a money motive behind the change) to the Paint folks and they loosened their standard and say something like 'this horse is off-type' on the papers.
So for the time being in these breeds of chickens:
-if is is rumpless and maybe tufted (its a lethal trait if you get two copies so they will never remove the a-ok to be non-tufted) and lay sky-blue eggs you are an Araucana (US only)
-If it meets the strict breed standards for Ameraucana including only being one of the 8 accepted colors, it is an Ameraucana
-if is generally resembles a bird that might have either Ameraucana, Araucana lineage, or lays blue eggs, it is called and Easter Egger
Clear as mud, eh?
