Is the RIR with the big comb and wattles that's higher up on your arm a cockerel or a pullet? I'm noticing that the pullet lower on your arm is in very submissive positions to that one, and has way smaller comb and wattles. The color difference in comb and wattles is also significant, and the legs on the higher bird actually look male to me. But I can't be sure because I can't see hackle or saddle feathers due to the angle of the pictures.
