Araucana chickens were brought to the UK in the early part of the 20th century. They made their way to Australia via New Zealand in the s. During that decade, the British geneticist Reginald Punnett found that the gene for blue eggs was dominant over that of white eggs. He also found that crossing Araucana chickens with chickens that laid brown eggs produced birds that would lay olive or green eggs. Araucana chickens can be bantams or large fowl. They have tufts of feathers on their ears and are often rumpless or tailless.
Large fowl can be white, silver duck wing, golden duck wing, black-breasted red, and black. Bantams can also be buff. Read more about Araucana Chickens. The Cream Legbar is a chicken developed in Great Britain. The Cream Legbar inherited its blue eggs from Araucana.
Auto sex chicks are those born with traits that enable people to distinguish males from females on the day that they hatch. In Cream Legbars, male chicks have a light coat and a yellow spot on their head, while female chicks have stripes. Adult Cream Legbars have slender builds.
While both sexes have cream-colored necks and mainly gray bodies, the male has a cream colored-saddle and gray chest, while the female has a salmon-colored chest. Cream Legbars are described as having calm and friendly dispositions. They also enjoy roaming outside and are thus usually raised as free-range chickens. It is still quite rare in the United States and is not yet a recognized breed there. In , the Cream Legbar Club was established to encourage the keeping of Cream Legbars and eventually get the breed recognized by organizations like the American Poultry Association.

The American Poultry Association recognized the Ameraucana as a legitimate breed in The Ameraucana can be either a bantam or a large fowl, and the males are heavier than the females.
In bantams, the females weigh between 24 and 26 ounces, while the males weigh between 26 and 30 ounces. In large fowl, the females weigh about 5. The Ameraucana comes in eight colors: white, wheaten, silver, buff, brown-red, blue wheaten, blue and black. Its pea comb and wattles are both red. It gets along well with both humans and fellow chickens.
It is independent and enjoys free-ranging. The Ameraucana has a life expectancy of about seven or eight years. Log in. Product Search: go. Help Me! OR: Search by Category.

The eggs from the grocery store are so flat compared to eggs from my hens. Is it because my hens are pasture raised? What could cause that? What breed do you cross Ameraucanas with to get Easter Eggers? What breed lays easy-to-peel eggs? This is because the bloom, put on right before the egg is laid, contains a fair amount of pigment. A hen will not change eggshell colors throughout her life; although, toward the beginning of a laying cycle the hue may be darker than towards the end of the cycle.
Some chicken keepers discover even more unique egg colors, like deep pink, dark green or speckled, by crossing different breeds. When a hen and rooster are mated, genes from both parents contribute to the eggshell color laid by their offspring. Some of the most popular crosses are called Easter Egger or Olive Egger chickens. Easter Eggers can lay a variety of egg colors, from blue to green and sometimes even pink. Olive Eggers are aptly named for the olive-colored eggs they lay and are a result of crossing brown egg layers with blue egg layers.
How chicken egg colors are formed All eggshells start white inside the hen, because shells are primarily calcium. Blue egg layers add pigment early in the shell formation process , which is why these shells are blue all the way through.
A combination of blue and brown pigments produces a green shell color, as with an Olive Egger. Hens that lay white eggs do not produce any pigments during shell formation. Hens need approximately 4 grams of calcium per day to form each eggshell.
