Ok. *inhales*
Ameraucanas were bred from Araucanas, to preserve the blue egg gene, while eliminating the lethal tufted gene.
They come in set colour variations.
Can't list them all of the top of my head, but I remember some.
Wheaten, silver, white, black, buff, and red wheaten.
They must be muffed and bearded, clean legged, have small or non existent wattles, and a pea comb. They lay various shades of blue.
Easter Eggers ('Americanas'- hear the contempt in my voice, hatcheries) are complete mixes. They often lay coloured eggs. They can have any features.
