That's a hard one. It has female coloring, but boy it's comb and wattles look boyish. Sure it's not a black sex linked? They look like female coloring barred rock, but get the big comb and wattle early.
It doesn't appear to be a Barred Rock. The chick looks boyish based on those pics. I'd say post pics back in 4 weeks for a more accurate assessment. I ended up with a Barred Rock mixed that appeared boyish since a few weeks old and it actually ended up being a commercial black female. She's beautiful and love her. So give it some more time to guess more.
