We have a couple of Spanish Araucana chickens at home, and they lay BLUE EGGS! History research shows these chooks have been doing so since the 15th century in Spain, as Spanish General Cabot noted, and by the 1800’s the chook was spreading throughout the world, known for its blue eggs and ability to produce almost 200 eggs per year. On the inside the eggs are the same as white or brown. They are simply beautiful and such a wonder of nature! Oh how I love or little Spanish ladies!!
