About the last mystery chick with the blue head:
Her head is blue, with yellow coming out on her neck more and more.
It looks golden yellow and blue in the sun.
Someone guessed when she was a chick that she was a BLRW....but she does not look very BLRW to me. Not enough B not enough L...too much W?
BLRW stands for Blue Laced Red Wyandotte. She's definitely not one though. She could be a mix of sorts, possibly with some game. I really love her coloring!
