Can anyone tell me what to look for to figure out what my little one is? I will try and post a pic later. I ordered a dominique, but I am pretty sure she's not a dominique ( no rose comb). She is 4 weeks old, has yellow single comb and a yellow legs with black wash down the front. Her feathers are dark with a mottled look, mostly black but def has the barred look. I asked MPC and they said I probably got a br or marans. I did allow for substitutions and I am not upset she's the sweetest most friendliest chick. What's the major difference in Marans and Barred Rock?
