This what a BSL would look like. Your chick looks nothing like this, definitely a Golden Laced Wyandotte. BSL are solid black and have red on chest and neck ONLY and is not that spread out. Also BSL chickens have a green tint on their feathers, and don't have as dark of a face and beak as Wyandottes do. Hope this helps.
