I am hatching test eggs from my mixed flock right now and got some interestingly colored chicks! They are from a blue hen and have blue, black and white roos in there. What mixture could have produced these colors? This blue hen has been proven to throw blue, black and splash babies in the past, no partridge. The first chick (the dark one) has a black undercolor and red/brown on it's chipmunk strip and cream markings on it's head (these looked silver right after hatch). The lighter one looked silver right after hatch, though it was a splash, but now it has yellow or buff fluff in there. They are adorable, I am just curious what you would call them? Black partridge?
