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. Blue Rocks are quite hardy and cold tolerant.
Also known as: Sapphire Rocks, Sapphire Blues, Sapphire Blue Rocks, Plymouth Blues etc.
