Dutch Bantams are "true bantams", meaning there is no standard-size version of the breed. These fancy little guys come in a ton of varieties like Partridge, Golden Duckwing, Silver Duckwing, Blue Ducking, Cukoo, Blue Golden, Self Blue and others. Dutch Bantam hens are very good setters/brooders and make good, protective mothers.
