I just bought some young hens last night, two of which were supposed to be Barred Rock. However, when putting them in the coop, I noticed one looked different, had more of a lace pattern. Also, her color is lighter, more of a gray. But her legs are definitely yellow. I took these pics early this morning, so I had to use flash. If I get home in time I may be able to take some better pics this afternoon. Any thoughts on what I have?
