Some hens lay eggs blue
And they can be used in pischu
If you ask someone what color eggs, you call two options: brown and white, and will be absolutely right - the majority of these birds are born just such eggs, but there are exceptions to the rule.
Some breeds, namely Araucana, dongksiang and lushi differ from other members of the species chickens: Their eggs have a pronounced blue-blue color.
Chickens Araucana appeared in the mountainous regions of Chile and got its name from an Indian tribe of the same name, which was engaged in their cultivation. Later chickens spread to North America, which became known as the Mapuche. The first mention of chickens scurrying blue eggs, dates back to 1526, the year. Chickens and dongksiang lushi comes from China, where they were bred for more than 500 years. As long ago caused some chickens to change the usual color of the eggs?
Scientists have discovered that the culprit - a gene mutation SLCO1B3, responsible for the production of one of the pigments contained in the eggshells - bilirubin. Once upon a time the ancestors of modern chickens infected endogenous retroviruses EAV-HP, which introduced its genetic material into the DNA of healthy cells, resulting in a surplus of bilirubin and as a consequence - blue eggs.
Mutation Araucana chickens differs from the variations in the genome of Chinese chickens, which suggested that they are caused by two different outbreaks of retrovirus. I must say, changes in the body triggered by a virus, do not represent any danger for birds, as well as for the person eating them, so the blue eggs of these species are now in high demand because they have gentle and refined taste.
