I bought 6 chicks at the feed store, 2 of them were supposed to be Barred Rocks. But where are the "bars"?? These (I hope) girls are 8 weeks old. My FIL says they'd be barred by now. What they are is HUGE compared to the other girls. Are they Jersey Giants?? As chicks they looked like little penquins, black on their backs, grey by the wing and yellow bottoms. (sorry I can't get the chick photo to upload) All advice appreciated!
