I have a 12 week old Black Copper Maran x Lavender Orpington "Chewy" that I got at two days old from a friend. I have not been able to pin point if it is a pullet or cockerel? I don't have any experience with either breed, Chewy's feathers are not like any of my other chickens, ( I have ISA Browns, Slikies, Red Indian Jungle fowl, and a D'uccle) they are so fine and extremely soft. they are softer than my silkies. Chewy has beautiful purples, blues, and greens when the sun touches it feathers.
