it might be too old to go by the feather sexing techniques for a RIR. but if it's not here is what they say, a female will have uneven wing feathers a male will have a even row. however if they are too old I think they both eventually become the same. but if it's not too old the even feathers would indicate a male. but let me be honest, I think it's a bit old for wing sexing so I wouldn't trust that..wait to see if comb redden early. if yes, then it's male. female combs stay pink until point of lay. hope this helps. it sure is cute!! ♡♡♡
