Hello - new to chickens and to this website, dying to know if this little BO is a pullet, as she is supposed to be? I have a mixed flock, all should be pullets, and this little one is feathering much slower than the others (have an EE, D'uccle, polish, cuckoo maran), although I don't have another BO to compare to. This pic is at 3 1/2 weeks old. No sign of red on the comb, and no wattles to speak of. Thanks for your help!
