blue eggs (nearly Easter)

This is in my occasional series of Egg Photographs (if the eggs are lucky, they're turned into digital negatives and thence, appropriately, into albumen prints).  These were elegant eggs; Araucana eggs; eggs from birds that may go back to pre-contact hens (originating in Chile) - which would make them the only eggs from chickens originating in the Americas.  But.  These eggs are a delicate, extraordinary, pale blue.  This is the result of a DNA retrovirus that occurred sometime early in domestication.  It's really hard to capture this blue, it turns out ... and I can't go back and rephotograph these eggs: I cooked with them.
