I'm leaning hen as Robin is. Nice bird. It's an English Copper Black Maran since there are no feathers on the feet, (which would be French). There are three color types of Black Maran, I'm leaning Brassy Black because in Marans the feathers have a moderate sheen which was historically bred from the Golden Necked Black. But at five months, it's still young and hard to say for sure. Great birds with a good temperament. They don't often like a ton of human handling.
