I bought 6 chicks from our local Rural King that were supposedly Dominiques December 18. They were all in the same bin but are obviously not all Doms and probably not all pullets or even the same age. I am enclosing pictures below. Thank you for any help. I am pretty sure this is a roo. He is developing a rose comb so may actually be a Dominique. Straight comb, dark beak and legs so maybe barred rock pullet. The one with visible head has a rose comb, dark beak and legs but comb is pinking up already. The second next to her has a straight comb, dark legs and beak but very indistinct barring. This little one is obviously much younger but only developing wing feathers at this point. No tail. Last another with straight comb, dark beak and legs.
