The Blue Rock results from crossing Barred Plymouth Rocks and Blue Andalusians leaving us with a sex-linked, production breed. These striking birds are monochromatic – hens being largely light gray fading into a charcoal head. Your rooster has that same light gray bottom half but with charcoal barring from the hackle to the tail. As chicks they have a lot of variety in color, ranging from nearly lavender to black. Blue Rocks are quite hardy and cold tolerant.
Also known as: Sapphire Rocks, Sapphire Blues, Sapphire Blue Rocks, Plymouth Blues etc.
