It's a Lavender Orpington. Typical quality for hatchery/backyard bred Orpingtons. He's not crossbred. That off-color is often seen in birds. It's called leakage and has nothing to do with anything but him lacking the melanizers to be evenly black so the Lavender gene could dilute him to Lavender. Instead, he's a leaky Black with a Lavender gene that turns his red leakage to gold.
