Hi! I read several posts commenting on the rarity of blk/wht EE pullets. I had no clue! Two of mine are in that color range and their 3rd sister is sort of blue grey with some golden brown shading. these birds are actual sisters out of a black&white 'silver' Ameraucana rooster over 4 blue & brown hens I had picked out at the hatchery but had to give away to a friend when 'busted' for illegal chickens, (once the city OK'd a hens only ordinance, my friend gave me 4 daughters - one of whom turned out to be a son and was re-rehomed). Here are my girls, all lay blue or turquoise eggs.
Sorry, the 3rd bird (with the muddy blue/lavender coloring) is camera shy, though she lays the pale blue eggs. Here is a box of my eggs, the tan ones are from a Dominique and the red-brown ones are from a Welsummer.
