The RiR is 7 weeks old so it may be early to sex. I've been leaning to rooster because his comb and wattle seem to be darker than his clutch mates but he is much smaller than them. I'm guessing the other one is a Polish rooster but is much harder to sex because I have zero knowledge of polish chickens and I'm not 100% sure its age. We have had him for 6 weeks. Just after opinions and think it's fun trying to guess their sex.
