I recently bought a trio of RIR, two hens and a rooster. Regrettably I didn't ask their age, so I don't know where to even begin id'ing him myself.. I've gotten mixed remarks about whether Kingsley is a roo or a hen, so I figured I'd ask here, since everyone here is so good about answering my noob questions! He's got gorgeous black feathering on his neck and wings and tail, totally unlike my 11 RIR hens. Also, could anyone age him for me? I'm thinking 8-12 weeks, but it would be nice to know when to expect him to start crowing and doing his thing.
