My chicks are almost 7 weeks old. None of them have a red comb, many have no discernible comb at all. A couple have very small combs and a few small combs with a tinge of pink at the base. A few have pink-dark pink skin wear their wattles will be but no wattles actually hanging down at all. My barred rocks are far more black than white. All my EE are of the 'chipmunk' color variation. No white on any of them but quite a bit of red on one. I've got BR, BO, EE, Australorps,RIR. I know nothing is guaranteed until they lay an egg or crow but by 7 weeks little roos should be looking somewhat roo-ish right? I had prepped myself that with 25 'pullets' I should expect at least 1-2 roos or maybe more.
