Chicken Ameraucana
The iridescence of the Americana's feathers is quite spectacular, but the dark colouring also makes it hard to find it's eyes! And it really does lay greenish-to-bluish hues of eggs.
"The Ameraucana is an American breed of domestic chicken. It was developed in the United States in the 1970s, and derives from Araucana chickens brought from Chile. It was bred to retain the blue-egg gene but eliminate the lethal alleles of the parent breed. There are both standard-sized and bantam versions." -- Wikipedia
